Stuttering, lurching engine, anyone have any clues?
I was driving down the street tonight, just filled up with gas, temperature of the engine was normal, tuned her up about 18k miles ago (plugs only). The car started stuttering, lurching forward when the gas pedal was pressed. I engaged the clutch, idle went to normal, let it out a bit and hit the gas. Same thing. It died in the intersection. I restarted the engine and coasted to a stop. Idle was normal, car still lurched and stuttered. I popped the hood, everything sounded fine. I revved it to about 5.5k rpms for 15-20 seconds. All symptoms are now gone. This has happened before. Any ideas what this might be? Plugs are new, wires are good, O2 sensor was replaced about 12k miles ago. Don't know about the cap and rotor though. I don't know what else this could be. Any guesses? the car's an '84 with 90k miles.

hey oi!
since it happened after getting new gas, i wonder if you perhaps ran the tank near empty and got a little water or contaminants running through the fuel? |

Could be bad fuel, could be an intermittent signal to the DME, or weak spark.
My feeling is that the car's running too rich, I'd take to a shop to see the mixture. Ahmet ------------------ It's all the driver... |

Thanks for the replies guys! Black, I doubt it could be contaminated fuel, but think it more than likely is the fuel filter. I have no idea when the last time it was changed was. Perhaps that could have something to do with it. 1.2, thanks for replying. Good to see that you are still around.

Injectors. Where did you fill it up? A few years ago when we still had out 928 we had the same problem, filled it up at ARCO (not me by the way). Went and got some techron and the car ran smooth again. Yes everyone Techron DOES work miracles and ARCO doesn't.
