Well, I would plug the O2 back up and see what it does. If it goes back to being in limp mode, then replace the O2. Do you have a 4 wire O2? If so, I have a good one you can use. If it doesn't go back into limp, but you still have idle issues, try adjusting the idle valve on the throttle body(if that applies). Also use a timing light and adjust the timing if necessary. Let us know what happens.
Ya im going to fix the oil issue first,as far as the 02 i have a few laying around ill give one a shot,and the idle is adjusted about as high as it will go,im sure its in need of plugs again.But it also surges as well,this damn car is a head ache.
OK car now starts and runs good,but now when it gets up to temp and im driving,if i take my foot off the gas like to come to a start it shuts off. It wont hold an idle when its warm,but revs freely.
Any ideas,i was thinking since it has a walbro 255,and stock fpr that may cause a dilemma?
Alright, 2 problems down, hopefully - 1 more to go! Ok, start by checking your IAC valve. Pull it off and clean it if need be.
Well it did this same thing on the old motor,and this is a completely different swap,nothing from the old motor is on this one. Dyno inc was able to fix it when they tuned the car and adjusted my air fuels,thats why im thinking the fuel pump is causing something.
Edit:im going to buy a new harness,im thinking the plug for the engine temp. sensor is shorted somewhere it is throwing the air/fuels off when the engine is warm.
Btw a while back i removed all of the emission crap and the charchol canister.
