I just fixed my '98's rear axle and swapped a JY door on. Me and a couple buddies went and bombed some puddles. When I got home I had a high (~1800RPM) idle. It now does this when started.


Just looking for any ideas or common issues before I get into it due to time constraints.

Thanks

 

Check for vacuum leaks.

 

Never hurts to check your IAC and TPS as well

 

Thanks guys, hope it's something simple

 

The throttle position sensor hates water.

It would be a primary suspect considering that you were just puddle jumping prior to this symptom.

 

Roger, ill take a look when I get some shop time. Thanks

 

I finally got a chance to mess with the jeep and the high idle is gone now, so I'm assuming it was a wet TPS. Still have a CEL tho

 

There is only one strategy with a check engine light. That is to read the codes.

For a 2000, you will need either a scan tool or a code reader, or you can bring your XJ to a parts store like Autozone where they will read the codes for free.

When you get the codes, post the EXACT code numbers here. Not just a description. With OBD codes, the devil is really in the details.

 

Drove the Heep into town then to a buddies house, CEL gone now.

XJ FIX SELF, SO EXCITE!!
