Hey guys,

I need some help here. I've developed a real stumble on my car. It can happen at any speed and any rpm. If i accelerate or recel than I can usually get it to stop, but it's been getting worse and I have no idea of what can cause this.

thanks

 

i also get this at times i think it might have something to do with spark getting to the plugs

 

When I first bought my car, it would stumble under hard acceleration. Fresh set of AC Delco plugs and it was as good as new.

 

i put new ac delcos rapidfires in and it was fine i think its just my coil going now and its not under hard acceleration just a few times a week it might happen

 

Make sure the ignition timing hasn't changed due to a loose distributor bolt. I've had mine loose when setting the timing, reved and the dist would creep closer to TDC on every test rev. A big symptom is mainly using more gas, or louder than normal exhaust and lack of power in some cases.

Hm, also check for vacuum leaks. Could have a leak that happens on occasion like with a cracked hose.

Things to check:
1) Coil,
2) Cap, Rotor, Module
3) Loose cables
4) plugs
5) as mentioned; timing.
6) those connections to the coil, and the dist (the little 18 gauge wires with plugs and stuff).
