My jeep started acting strange yesterday. It would run great cold, but when it gets warmed up it stalls. Got in it today and it does the same thing. I can start it up and it will idle while I clean it off, I take off and drive like 2-3 miles then it will die at stop signs/lights. It doesn't seem to idle after it warms up. My battery is brand new (3 months old) Any ideas? |

TPS sensor possibly could still be the battery though, but usually if it's the batt it simply won't idle, warmed or cold when it dies at stop signs does it jerk?? if so could very well be the torque converter |

I'm new to wrench so how hard is the TPS sensor to replace and how would I find out if that's what it is? |

they're about 40 bucks if you have a volt/ohms meter you can check the tps drive it by advanced or autozone, it may be giving a code without a check engine light however if ya have a volt/ohms meter you can check the tps in the following way turn key off and hook meter ground to ground on battery you'll use the red to probe the back of the connector where it goes to the wiring harness at the tps signal return wire is usually black, meter set on ohms you should get 1 ohms or less turn ignition on check the reference voltage it's usually orange, should be right at 5 volts then with the throttle closed, check the signal wire, its probably green, sometimes brown/white or green/brown should be about 1v then with the signal still probed, roll the throttle slowly until it's wide open, the voltage should change smoothly and max out at about 4.5 volts i've never had to do it on a KJ but i've done it many many times on other vehicles and it's a pretty standard procedure heck with scantools now days there's probably a tps automated test |

Thanks JeepinJarhead03, I'll run it by Advanced in the morning and see what they say. I'm new to all this so I'll start there! |

Went down to Advanced & Autozone and they both say that their testers only work for codes and that I'd need to take it to a shop. So I'll take it to my local shop tomorrow after work. |
