View Full Version : LT-1 hesitation/stalling

2 questions:

I have a slight hesitation (stumble) on acceleration but then she pulls real strong. Plugs are new, wires are pretty new also. It only happens on the initial hit of the throttle. I'm thinking maybe TPS?

Sometimes on restart the engine quickly stalls and won't restart unless I punch in my code on the keyless pad (My '93 has keyless ignition) BUT, today it would not restart after several tries. Finally after about 8 tries it started. Wondering if my TPS might be causing this also?

JimN if you read this I'd be interested in your opinion.

tps and idle air control, I'd start there

That's what I thought. Can I check them using an ohm meter? I'm guessing if the TPS has a dead spot it will show on the ohm meter.
