Dont be like me once, and used non caustic (non-flammable) brake cleaner!
=)
I'm sure you've checked the fuel dizzy boot, underneath, for cracks in the
accordian section?
Also sounds like the ign. isnt adjusting on throttle tip-in.. have you
verified ignition timing functionality on rev increase? Fuel filter?
Sticky fuel dizzy plate?

Subject: [a2-16v-list] Mis-fire from idle...
I'm now officially frustrated and confused - I've been working on getting
an '89 GTi 16v back in fighting shape for use as my commuter/autocrosser
since late August. Yeah, I'm slow - sue me - between club racing, Grand
Am Cup and Enduro races, I've been a wee-bit busy and working in a hot
and steamy (or now ice-cold) shop wasn't extremely enticing.
In any case, the symptoms are that the car stumbles significantly off
idle. However, once the rpms hit about 2000, it revs freely "like it
should". The car has fresh injector seals, plugs, cap & rotor as well as
a new timing belt. I've checked the cam and ignition timing and it's
spot-on. I've also done the old "spray all the possible vacuum leak areas
with brake clean" to check for leaks to no avail. Any thoughts or
suggestions? Coolant temp sensor?
I had the Rabbit Truckette parked next to the GTi over the summer while I
had the injection pump rebuilt - maybe it hexed the GTi so that I wouldn't
sell the Truckette in Spring...
I'd keep banging my head against the wall but the wall is starting to
crumble...
Thanks all!!!!
Matthew
