Well it has been cold here for a while. and since it has my car has done this weird jerking thing. When i floor it the car will jerk and then will go. Even when fully warmed up. I just want to know if this is a normal thing for the MSP in the cold. it never did this in the summer, or fall.

Yes MSP's are wierd, but what are you boosting? If your boosting 9-10 and it's cold you'll boost a little moer and hit fuel cut.

[GhostMercury]

no im at stock psi cause i thought that was the original problem.

what exactly is it doing?

[JDM Sam]

Where is your MAF & IAT mounted?

[GhostMercury]

everything is stock location. but my mods are in my sig

hook up a digital multimeter to your maf and see how close to 5v you are getting. With the 626 intake manifold you are moving more cfm at the same boost level so you might be hitting fuel cut. What kind of gas are you using?

[Boosted03MSP]

Its too cold out. Relocate your MAF and turn the boost down a bit. Dont run it too hard in the cold, or boom :(

[GhostMercury]

i dont have the 626 mani. so is this ok, like did i mess something up?

[jeffmsp]

check your maf to see if it is maxing out. multimeter should be $10 or less, buy some wire to run it into the cabin. Tap maf with wire, attach other end to multimeter aligator clips, see what volts it is reading.

before i get started on all of the technical stuff. could the really cold weather just be causing this?

[orng1]

Yes.....

[GhostMercury]

ok good cause im saving money to add performance stuff. not fix broken shit lol.

my car did it the other day when I hit boost and it was -5F outside. actually it did it twice.. so that's what fuel cut is? interesting... :P

[GhostMercury]

alrite good. because i was getting worried. but i have a question. will it do the same thing if you get a co2 intercooler sprayer?
