'89 Auto EFI Misfires and Stalls at Idle/Low RPM
My car is giving me a serious migraine.
As specified in the title, it is an '89 auto, fuel injected. Earlier this week, my car started misfiring at long stops (car being up to temp at the time). It only happened once the first time, and it was like the car lurched forward out of nowhere. The second day, it happened a few more times, always at long stops while the engine is hot. It finally started stalling out yesterday, though it will immediately crank and turn over after a stall with no objections. I can muscle through the misfires and prevent a stall as long as I keep accelerating. Any slow downs or stops and it falters and will stall if I don't punch it. This happens in drive and in reverse, which I found out yesterday. The VAF is perfectly clean, main intake hose solid, no apparent vac leaks, distributor cap new and clean, throttle body clean. I tested for spark and all good there. I'm literally at a loss.
Any suggestions? Thanks
