OTC. Amazon I think...

Alright, first I wanted to thank everyone for their help on my start/idle issues. I spent an hour today testing the camshaft sensor and crankshaft sensor. I then replaced the OPDA, which I plan to do since it was original.

When I started the car again, it was running worse than before, so I loosen the bolt and twisted it. With a little bit of tweaking, I found the sweet spot and the car runs perfectly again. Apparently it was the OPDA all along. My brother must have hit it when we were performing the MML. Again thanks for everyone’s help.

If you get a cam/crank mismatch code, you may have to tweak it again, or find someone with a scanner that will read cam/crank alignment.

I've always just done it by trial and error if it threw the code.

apparently the car runs better with the crank position sensor unplugged then when it’s plugged in.

Is this unique to the 05/06? I swear my 97 won't start at all if either the crank or cam sensors aren't plugged in.

Yes. Different PCM, cam and crank tone wheels.

 

[hear]

I know that, but the PCM still has to know the angles & rates of change, and if they're disconnected it ain't gonna know. Or is this where safe mode enters into the picture?

 

[JKP]

It can get enough information off either the crank or cam sensor to run on just 1 of them.

It won't run with both disconnected.

Which is good, since you won't get stranded if 1 fails.

It's bad if the OPDA gear breaks and it keeps running without oil pressure...

Tummy tuck is when you lift the tranny and transfer case and replace the stock (shovel) skid plate with a high clearance skid plate. The result is better clearance and it looks better

New to Jeeps... Is this caused (or exaggerated) when a lift is installed or does it occur regardless of a lift? If it is "factory" seeing, wondering why this is is set this way? Thanks!!
