Hey guys, Just after a few ideas regarding a 94 VR6 (so assuming obd1).
The idle is rough when starting, jumping about which ive read is a normal thing, it jumps up as high as 1300 and drops super low, also frequently shutting off. This is mostly when starting, but regardless of warm or cold (although obviously more prominent in the mornings/when cold). So far Ive fixed a few things, and theres a few more to go, but would any of these have affected it?
First, The breather box off the ISV was missing, but recently replaced that and cleaned out the ISV, which was pretty filthy.
Then the fuse for "engine elektroniks" was blown, so replaced that, but it didn't seem to change much which I thought was strange
The coolant hoses were replaced recently, but the hoses to the throttle body were not attatched, could this affect idle stability?
The coolant is also quite low, would this affect the idle in any way? I noticed that once the thermostat opened it seemed to idle steadily on 850ish-rpm
In short - what the **** can I do to fix my idle!
Don't suggest a vag scanner unless you've got one that you want to use on this car
Any help or suggestions much appreciated
