Youve prob. flooded it to hell buy now. Watch out for hydro lock. If severly flooded, pull plugs, disc. fuel pump and coil wire, crank it clear. Ive done this too before (lost original reference) by diss. sensor plate assy. Put it in the. middle, you can manipulate the sensor plate by hand till you get it close enough to idle.If you are exper. enough you can tell with your nose, idle, and just cracking the throttle body to get it close, But if you don't feel you are knowledgeable enough to do this, to be safe for high rpm afr's, on a non 02 car, you can rent a gas analyzer from you local parts store, and set it to spec. 3.5 on a non 02 car i think, specs are in the Bentley. Aparently it did not fix high idle prob, ( it usually dosent, as there are numerous other things that cause high idle) Start looking for vaccuume leaks, bad cis components once you get it to start. Just remember, everything you adj, effects how other things work to. Fix vacuume leak, idle is to low and must be adjusted. I saw a guy adj. his idle once by moving his dist. around. Talk about under informed.

Thanks Don,

I'll give that a shot and yes she is a tad bit flooded!
