i just boosted my car and its not tuned yet but when i start it up it idles at 1500 and also sounds like the car is miss fireing! it will idle smooth for a few seconds then misfire then smooth then again! its a gsr with a un chipped p28! thank you can some let me now whats wrong with it

 

any 1

 

are you running the stock injectors?

 

yea

 

are you using stock plugs? and did adjust your dist timing?

 

clean ur iacv and adjust ur idle screw accordingly...it should idle around 400-450 rpm with out dying, when the iacv is unplugged...then should idle at 800-850 rpm or so when its plugged back in..

 

you didnt go beating on it now that its boosted and untuned did you?

 

bump

uh oh...i have a hunch

 

ummm maybe do a coil test, and an ICM test

its pretty easy to do you just need a multimeter

just search the ohms and test points on ht
