I have an mk4 jetta GLS vr6 12v 2.8, the cars ran great ever since i got it replaced water pump all the componenets tonthe enginw pretty much everything new etc. But recently i have a problem where the car intermittenly does a weird idle down like if it wanted to stall then recooperates and its only when coming to a stop or when i coast in neutral, but the car runs and drives fine, ive recently fixed and SAI vacuum leak and worked okay then back again this morning does anyone else have this problem and or what can be done, an important factor is i replaced my throttle body as well when my ecu fried due to the bad TB but got the ecu thing done like aboutba year ago and recently started with that problem, hopefully its a simple fix like possibly switching out another throttle body and or anything else???
