I have a 1991 Jeep Wrangler and last week it started to idle high 3000-5000 rpm. This morning was he coldest yet and it would not start. I replaced the tempature sensor, spark plugs, distributor, air filter, crank shaft sensor and wires. I live in Nrth Florida and the tempature recently changed drastically. I did not have this problem in warm weather.
Unpredicatable start

Jeepz.com, freezing up?
Do you have power when you excellerate? Or does it seem like it doesn't want to go with high RPM.

91s don't have carbs
Sorry, I've never owned anything but an 85 or earlier AMC. colerie said that there was a good spark on the plug end so working simple to dificult on the troubleshooting, I wonder about fuel then timing (new distributor?), over-gapped plugs...along those lines.
Can you get trouble codes on a 91 using the odometer button?

No, but you may be able to get them using the three cycles from off to run, leaving the key at run and counting the flashes of the check engine light.
