idle problem

[satyr36]

Didnt drive the car for 2 weeks. drove down to get gas, on the way back car dies at the stop light. Drove it home, idles very bad. Changed the spark plugs(was due) didnt help.

Idled the car at 4k rpms for a second to pop any CELs i may have, P0300 Random/Multiple Cylinder Misfire Detected came up...

On my boost guage it only showing -12 or so at idle. Should be up -19 area... I cant find a leak ANYWHERE (dunno)

ignition, bad gas, etc.

what is the nature of the rough idle? is it just generally rough or is it erratic (up and down, but not always trying to die)?

[satyr36]

ya its kind of up and down, how can i check if its bad gas? lol i have a full fricken tank

should i syphon it all out? rofls

PS. i just called where i get gas and they said they have had no other complaints

cleaning your egr could help ...check the how to section for it

Yea i didnt drive my car for 2 months and my car was readin 9 at vac usually sits at 21-22 on my faze boost/vac guage. I was in CT and took my car to the shop spent 1000 trying to chase down a leak. All i needed was a new EGR valve cost 260 for parts and work. Hope this helps

either EGR valve or MAP sensor would be my bet.

MAP or MAF?

just cleaned the maf awhile ago.. few months that is

im getting ready to pull the EGR

dont know how that would be the problem as car was running OK. then all of a sudden started to crap out.... unless the more gas you give the car the more the flap opens? I guess it could have gotten stuck open

cleaning the egr might not be your problem ...but it will help your car idle a lot better and run smoother overall

egr is probably bad.. the spring wont even open and close the valve on its own.......trying to clean it up now but i broke a couple of the bolts on the top portion of it

I agree...probably the EGR.. the cold and moist weather causes it to rust and seize... my car did the same thing a few days ago, so I'm going to replace it with the new canadian EGR valve

with the amount of work and trouble taking that shit out, cleaning it is just retarded to me... might as well replace it with the updated part and forget it!

to make a long story short, I even replaced plugs and checked for leaks... everything is fine.... and after a while, the car ran OK again and hauled decent ass.... so it all points to the EGR to me

Join the crowd, I stripped the hell out of mine last night even after PB Blaster and they are still not loose.

how are you gonna get the canadian valve?? those are s'posed to be a lot better than the us ones right??

[axisboldaslove]

yes because they have a coolant line hooked up to them...as far as how the coolant line helps hopefully someone else can fill in my blanks......._____________________________________ _________.

go to canada and buy one :P
no, I can't help anyone get one.... there's been a run on them up there so the shit is major backordered and in short supply... maybe I would if it is summer where these stupid things don't fail as often

it heats the EGR valve and the heat cooks whatever condensation is built up inside rapidly in order to prevent/stop the condensation from causing the valve to rust up and seize... there is a vent hose for the vapors to escape

ok cool. i got it all cleaned up.. had to drill out the old screws then i just put new ones in with nuts on the back.. lol fuk it! works great car runs perfect~
