I havent gotten around to driving my car im trying to make sure it is in tip top shape before I start to drive it around again. It has a choppy idle and it idles down like its about to tie at times. I changed the oil never changed the sparkplugs but i cleaned them off really well end result still nothing.

I have nothing but 93 octane gasoline in the lines. My mods are for this car are injen piping. Cair injen intake megan 3 downpipe and megan 3inch exhaust no cat. thats it the turbo is stock the manifold is stock. What can it be? Car has not been touched since i brought it never tuned it? has anyone else experienced this before?

 

need a lot more info.

when did you buy it? how long has it been sitting? any check engine lights?

 

I brought it a year ago it was salvaged not sure how long it was sitting. No check engine lights at all there is a service engine soon since the airbags were recently deployed.

Its going for salvage inspection and i have not plugged the airbags back up since i replaced them just yet. But im sure that has nothing to do with the engine running with a missing idle thats it. Does this help I also explained my mods in the first post. Almost forgot a greddy profec spec b boost controller. And it is showing these numbers and **** dip up to -75 back down to -34 then it repeats itself over and over again. I think it has to do with the timing what gives?

 

1. Get rid of the greddy profec b, and get a good old mbc. 2. Get an ecuflash tune from an evo friendly shop!

 

ok thankyou

 

You might want to check for any vacuum lines old or cut.

You should do a boost leak test with a spray bottle of soapy water to see if you have any air leaks. Last thing is to check the ISC/IAC valve.

 

I checked vacuum hoses and pinched them down no good i did have some loose but thats good now. uhhh where can I fidn the Iacv on this car?

 

under the throttle body.

It is pictured there in black, 3 screws

 

How will this cause a lumpy idle? will this have an effect on the car how can i test this for reference since the car is not shooting a code?
