I think I'll just mismatch them to get an even castor angle. I'm out of ideas of other things contributing to it.

I had my 2001 XJ stall twice yesterday and today in the morning it wouldn't start at all. After it would stall it would start right up again. I thought it was a bad battery then I jumped the battery but it wouldn't start. I disconnected all 3 sensors on the throttle body then reconnected them again. lucky the jeep stated right away. Which one should I replace first?

100% sure. There's is no wire going to pin 10. I even tried hotwiring a wire straight to pin 10 and grounding it but still no high idle. Can anybody look at there jeep and tell me where pin 10 wire goes to?

When cold and I take off, at about 100-200 yrds I get sputtering and I give it more gas and I get a small back fire and then it is all good.
This week I was getting O2 Sensor Codes so I replace both up stream and down stream O2 sensors. Cleaned the IAC.
Still getting the same sputtering. Does not stall but I do get the small backfire. Once it backfires everything seems fine. No loss of power or shifting problems after the backfire.
Could it be TPS?

10-4 got 1 week vacation coming up want to throw one on without getting too involved. Like cutting the harness, next thing you know it'll turn into me trying to do the "big 3". Trying to keep it cheap and easy

Can a bad camshaft position sensor prevent my 2001 XJ from running? It cranks and cranks at times and it won't run. If I get it to run it'll stall right away. Only way I can keep it running is if I keep my foot on the floor until the engine gets warm enough for it to run on itself
