edit: This post is concerning my 87 2.2 T1 LeBaron Convertible that I recently rebuilt with a T2 turbo T2 Logic module and an 89+ Turbo1 intake manifold/throttle body/AIS/TPS.
Hey! I was talking about my bouncing idle from 1000 to 1100 in park and how it was rock solid at about 750~800 in gear.
Well when I start the car and leave it in park it will rev to 2000 or so right after start and promtly drop down to about 1500. After 15~25 seconds it almost seems like it's trying to lower the idle and does it too much or too fast and the car drops down to 200~300rpm or lower and just flat out stalls. If I hit the gas real fast at the 200~300 range I can bring it back to life before it dies.
This is getting on my nerves - as I have to push the gas and hold the revvs at about 1500 before I can drop it in gear or it dies on me. If I drive it a bit and park it I can put it in park/neutral and it will rev from 1000~1100 up and down but will not die on me - it only happens after a fresh start.
Timing last I checked (last week - done nothing to it since then) was at 12degrees BTDC cam and crank timing are good O2 seems to be functioning normally (A/F gauge) but O2 *shouldn't* cause such a problem so close to start (comp's not reading gauge till it warms up right?).
I was thinking either bad map sensor or bad AIS - but I don't have extras to swap in so I'd like to pinpoint the problem BEFORE I buy the new part =)
Any assistance is appreciated!
edit: Going out to pull codes - last time I checked (even with it doing this) I just had 55.
