Are you sure there are no air leaks anywhere?--)--------- yeah to me that sounds the prob,i will check today.
Intake manifold/plenum/throttle body gasket, vacuum line off/leaking, dud brake booster etc..--)----------------------------- will do proper check today.
-A scantool will help (ie check what the IAC is doing, if the car's staying on cold start and holding the idle too high--)-------------------------------what is IAC sopose to be reading at idle ??i have a scantool..
-Check your throttle body isn't jammed/being help open.--)----------------------------------------------will also check that today.
-Dodgy MAF?--)----------------------------could most likely be-it was throwing maf connection code, and makeing motor just stop random. till i earthed the E to the chassis hasnt really done it since, but still could be stuffed..
