Cold Weather Trouble in 2001 Cherokee
Every time the temperature gets extremely cold, my Jeep does something strange. It will start with no problem, but the second I take my foot off the accelerator it dies. I have tried letting it warm up several minutes. It doesn't help. Last time this happened, we kept it in the garage a few days until it was warmer and started ok. We took it to the dealer then and they did a full check on the computer. They found zero problems. Since it wasn't cold, they couldn't replicate the problem. It has run great since then, but now that it's frigid again, it is doing the same thing where it has no problem starting but won't stay idling if I remove my foot from the pedal. Again, they have checked and it is NOT the starter or the battery or the alternator. They found nothing wrong.
Does anyone have advice? I have heard there are fuel injection cleaners I can out in but I don't know which is best. I have over 139,000 miles on the car.
