can anyone tell me why removing the aiv pipes that go into ur exhausts either side make ur car run badly and not sit idle. my car wont run well atall and it wont sit without me putting a slight rev on it.

why does this affect the engine and is it maybe possible that iv got a cylinder on the go and its not really the aiv pipes under my car that wer cut off thats making it run badly.

car runs ok when giving it some after about 5 or 10 mins but it still spluters a bit and still dosent sit idle. cheers

removing the aivs did nothing to affect my 91 auto - you have of course to blank-off the exhaust intakes, and from memory the small diameter pipe at the balance bar.

 

good luck

it wont, as I said before they have mucked something up when the fitted the headers. snapped a bolt or missed a vac pipe.

im told that its because there's to much of an air mixture getting in threw the engine, is that possibly why its going like it is also told that its not a cylinder cause it wouldnt start to do anything till after about 5 mins of running so as to give it time to warm up.

also dont think they knew about vac pipe so that to is prob wots wrong with it

As per previous comments i doubt it is anything to do with the aiv pipes, after my decat they were left hanging down and the car still runs fine...
