Starting problem

falcon556 · Apr 10, 2005

MY '99 XJ when starting cold, it refuses to start right away, backfires through the throttle, and then runs very rough for about 30-40 seconds gradually smoothening up.
A minute later she is fine.
Tried pushing ignition wires for better contact, no help.
I checked for stored trouble codes, none. No engine light.
Any ideas?

Have you switched filling stations recently?

As soon as I finish this tank.

Had a similar problem that only happened when I gassed up at one palce in town. Just a thought.

Thanks, I appreciate it, sometimes the siple solutions are the best.

Same problem as described in a thread that I just started. Unfortunately the search I performed did not turn yours up first. I have a check engine light on and codes though. I am always on the road, keep the tank over half most of the time, and use about 5 different gas stations regularly. The problem has been persistant for a few months now.

Cross your fingers, a lot of knowledgeable people here, one of them has the answer.

I have this same problem, but no updates on this thread. Any ideas? Crankshaft sensor?

I filled the tank and the problem went away.
I have it in the garage trying to get the cruise control to work, so, I cannot say for sure it is cured from the little that I've driven it lately, still I think that was it.
