HELP !!! car turns off when A/C is on

[MIA protege]

i have a 2000 lx protege and im having some problems. when i step on the gas the car takes a while to respond. also, when i turn on the A/C and the car is stopped at a light, it will shut off completely. i dont know whats the problem. i do have an intake and i think i read something that they casue problems but im wondering if someone knows how to fix this. mechanics dont know whats going on so they just give me a shrug. my idle is very low, and when the A/C is on it just goes to 0 and shuts off. its also unstable when im on idle.... someone please let me know what the deal is. thanks

[MIA protege]

and i also have my CEL .... someone help lol. i dropped 187 bucks today for no reason for them to fix it and its the same shit (bang)

[MotegiMazdA]

they didnt find out why it was on? Brian (got wake?) said its probably a sensor. You check engine light should have given you a code for what was wrong. Go to autozone and have them scan it, they'll hook a computer up to the ecu and it will tell you what the problem is. Brian said his 2nd O2 sensor was going and his car started to run really shitty. Theres a how to for fixing it. Let me find the link

[Witchdoktor]

is it stuttering/hesitating any?

you still on your original MAF?

[MIA protege]

it is stuttering and they did hook it up to a computer and told me they were getting problems from the censor on the intake ... i dont know how i should go upon fixing it and i dont know if this is whats causing the A/C problem and the stuttering problem

[RyanJayG]

check the couplers and piping down stream of the MAF

[MotegiMazdA]

there's a recall on it for certain VINs up to 7years 70,000 miles. Im past that but if your not take it to mazda.

[Witchdoktor]

btw - get your 187 bucks back, that's BS bro

[MIA protege]

it wont happen cuz they charged me for fuel injection shit which i asked for since they said i needed at 60k miles. and i payed another 75 for them hooking it on to the computer which was bogus ... i dont know what the hell to do ... where do i take it to for they can check my mass airt flow ?

[Witchdoktor]

where do i take it to for they can check my mass airt flow ?easiest is to hook up with another 1.6 and try theirs out. it takes 5 secs to intall. call Mazda on Tuesday and see if your vin# is good for a free replacement.

btw - I'm on my 3rd MAF, salvage yard is the bomb (rockon)

[MIA protege]

danny ... why have u been replacing your MAF ??? were u having the same problem with the stuttering and the A/C turning off ?

say what ??

[Protege2K]

I am doing my best to not say that the 1.6 engine is why your car isn't responding when you hit the gas. ;) Which intake do you have, Injen or EBAY? Try making yourself a seal around the MAF to see if that reduces your hesitation. I am stumped though about the a/c problem.

[MIA protege]

its an ebay intake .... make a seal ?? im not too handy , lets just say that

[DiS]

Regarding studdering... You might have an air leak. Check all the couplings and make sure they are air tight. If thats not the case, then its your MAF. Sorry have no clue regarding A/C.

[MIA protege]

this is stumping me cuz it seems like the couplers are on fine

[RyanJayG]

do you have access to a OBDII scanner? any friends with one? I would be interested to know what your timing is doing when it does that kind of stuff

[Protege2K]

Come on Danny you're gonna need to learn these trouble shooting things if you ever go boost. The design on the 99/00 MAF is terrible when compared to the 01+. Go buy some bike innertube and trace it a little larger than hole. Cut it and install, should cut down on the hesitation. BTW, have you tried putting back on your stock intake?

[DiS]

do you have access to a OBDII scanner? any friends with one? I would be interested to know what your timing is doing when it does that kind of stuff

you can check timing with OBDII scanner?!?!??!!?!?!? Shit if so, Im gonna go do that once Ryan gets back on my post.

[hi-perf]

yes the MAF was a horrible design, thats why they had a recall for 7/70K. they said ok we f'ed up, so we're going to increase this for 30k more miles, and for 4 more years. go to the dealer if you have less than 70K.

if not do what witchdoktor does, go to a scrap yard and get a MAF. http://car-part.com is a good start if you're lazy, and you can get a knowledge of how much the part should cost.

you also got ripped off by the other mechanic "fuel injection cleaning" and the 75 dollars to hook up to the computer is the oldest trick in the book. though i doubt you can do anything now. just dont fall for it again, for that price you could have bought probably 2 MAF's and have your problem solved.

if i was you i would get a new maf, change plugs, and wires just to make sure you dont have a dying problem anymore. that can be dangerous if it dies when youre driving.

[MotegiMazdA]

Thats what I had to do with mine, I put my stock intake back on. Afterwards I had a CEL and took it to the autoparts store where they hooked their computer up to it and told me that I was having a misfire. problem with my 2nd spark plug and coil. I replaced them and waited a bit put my intake back on and I really dont have a problem now. Im not sure why. It hesitates every now and then but I really dont understand why its turning off when youyr a/c is on.

[Witchdoktor]

say what ??
verbatim - adv or adj : meaning the same words

[MIA protege]

ok ill try taking it to mazda first and see fi they can get me a new MAF ... but would they care i have a intake on there ?? cuz i heard they are bitches when it comes down to aftermarket parts installed on a car. i have a feeling the a/c porblem is cuz of this. cuz my rpms are so low with the a/c off that when u turn it on , it just drops below 0 and the car shuts off .... the car sometimes shuts off going in reverse too ... im going to go to mazda on teusday and see what they say. ill keep u guys posted and thanks for the feedback

[MIA protege]

verbatim - adv or adj : meaning the same words
not shiiiit lol

[MotegiMazdA]

if you are paying for the new MAF, then they really shouldnt have much of a say on wether or not they will do it b/c of your aftermarket parts. its a customer pay thing not warranty. Unless of course your car is covered under the recall...but they should still do it.

[MIA protege]

ok ... thank you jo

[MotegiMazdA]

well Im trying to clarify from a dealership POV. I work in service at Nissan so I deal with this daily.

Prepare for sticker shock if you have to pay for the MAF yourself at the Mazda dealer. I think I read on here that it is around 300-400 bucks. If they wont cover it under warranty, look at salvage yards before you spend that much.

deifnately will do that ... i cant afford 300-400 right now lol ... thanks

[Witchdoktor]

My second MAF was a refurbished one from Mazda for $100. Was $150 but they gave me $50 credit on the old one. It went bad quicker than the stock one - lol.

My third MAF was $50 from the salvage yard off a pro with 20k miles. So far so good *knocks on wood*

[Shane5425]

sounds like the idle up sensor went out, not sure where it is onth eprotege, it kicks up the rpms when ac kicks on at idle , if it doesnt kick on , the ac will bog the engine down untile it stalls at idle, Are you only having this prob at idle , or once you are going at 2k rpms the ac will stay on?

[MIA protege]

once im going my car is fine ... like if im on the highway me AC can be on without a problem.. maybe a lil stuttering here and there and slow of course lol but it doesnt turn off on me ... only happens when im sitting in a parking lot or if im going like 15 mph in a parking lot and i turn the AC on, right when i let go of the gas, boom , shuts off

[Shane5425]

i'd put my money on a iac selinoid.. it is located under your throttle body, it has an electrical plug in it, that kicks up the idle when the ac is on.

[OrngSpd03]

Sounds like the MAF to me. If your intake has an oiled filter the MAF sensor can become coated with the filter oil. This is only a problem if the filter has been over oiled. Sometimes they can come over oiled from the factory. If the filter feels greasy or leaves alot of oil on yor fingers when you touch it; there is probably to much oil on the filter. Intakes do not void warrantys. But damage to the MAF from oil is NOT covered.

[Beancho]

yeah i have had the exact same problem, same engine and i bought the same intake as you. At first i had no problems with it, everything ran fine. I got into an accident and while i was fixing my bumper i decided to make my intake short ram rather than ca because i was worried about shit getting in it cause in utah it snows a lot. About a month after going to sr i got an engine light, and the car started hesitating, but ive never had the ac problem. I cleaned the MAF with q tip and made the bike tube seal, i still had the problem. THen i went back to the ca config and reset my ecu. The problem seems to be gone for now, and the check engine light hasnt come on for about a week. Im also on my second maf btw

[Shane5425]

an easy solution to clean ur maf sensor is brake and parts cleaner, when i was changeing to cai, i sprayed my sensor with it to clean it , and it was horrible, i could see the dirt drippin off into a puddle left by the breakcleaner. i have only one complaint about my cai, on the highway cruising at about 2500rmps to 3000rmp , the rpms jump very iradically, if i give it more gas to get above 3000rmps its ok, but when it is cruisin at about 60 in that range of rpms, that hesitation sucks ass, i dont even notice it when i am in town driving around.. still havent figured out the problem..

[MIA protege]

im going to the dealership today if i can find some time. i'll see what they say about the maf
