Are U Here 2 take My Baby
Mine did this when my distributer need replacing. It would start up and barely be on, when i gave mine gas i could hear more cylinder firing but it wouldnt die, but the rpms would be sub 500rpm's.I replace my distributer and wires and she fires up and purs like a kitten
I definitley think that these cars need new plug wires and dist. caps more often than the average auto. I put all of the afore stated on less than 5k miles ago and are currently going to replace them for this build.
Pull codes.
Mine did this one morning. I got a code 11 or 12. I checked my resistance through my plug wires. Bingo. Plug one wasnt workin. Replaced it and voila! Runs good.

Mine does this occasionally too. It cranks with a low idle and then idles up to normal within 5-10 seconds. What would that be?
mine just started doing it this week, would be ruff, but after 5 minutes of warm up it would run fine
ok now its just sputtering all over the place, and i cant accelerate very well, I"m going to change the spark plugs, spark plug wires tomorrow, guess well see if it makes a difference
I have the exact problem but i am not sure if this is the reason yaet because i am rebuilding right now.
But I found this sensor unpluged and the point on the harness was ruined by the fan.

So, it is a sensor or the coolant is not going to the throtle body.

That sensor would cause the problem you're talking about. It is the ECU's Coolant Temp. Sensor. It needs to be connected. You should also be seeing a malfunction code for the sensor.
