Just started happening, i figure its a vaccume line somewhere but just wanted to see what you guys thought. This only happens when i put the clutch in, as soon as i do idle drops to like 400 and vacuume shoots to like 8ish and acts like it wants to die but doesn't. As soon as you let the clutch out its fine again. Anyone got any suggestions?
I just diagnose mine and fix it two days ago, thing is my only rev to 450-500 rpm at idle, when u rev it up it stumble to 100rpm and almost die, sometime it die. aafter checking, for leaks,replace egr,intake gasket ,injector,throttle body,plugs,wires, and vaf. it still does the same. then i parked the car for 2 weeks, came back to it on sunday,replace fuel filter since i havent in 7 years. and still no luck.
then im about to give up. i took the ecu off my other car,plug it in and baaam, the car runs and idle at 850rpm, so check /replace your ecu to see if thats the problem.
