OPDA issues...

So let's say for arguments sake that someone... lined up the holes on the OPDA as required to change it, and put a plastic pin the the aligned holes.

Then let's say that person was attempting to remove the bolt and accidentally turned the OPDA itself.. and the plastic pin broke.

Should said person pull out the plastic pieces and turn the engine over to re-align it or should this person try and turn the OPDA back into position?

Asking for a friend...

I dont have an opda but if its like a distributor it has to be in a properly clocked position or your engines not going to turn over or going to throw a code

It's a little different than a distributor. I owned a '97 TJ myself and yes understand that.

Thanks though!

If all you did was move the OPDA housing and not the motor, just realign the holes, use a pin punch to hold the housing in correct alignment.

Haha okay that's what I thought. "He" did have a pin it, but it broke.. this time he used an allen wrench.

So I got the old one out.. the old one's sensor is fused in and there's no chance of getting it out. I tried to remove it and now it's broken into bit, but the sensor is still in there!

So got everything set and aligned on the new one and getting the P0016 code. Made sure I'm TDC, not 180 out.. pulled the first spark plug and everything. Did this at least 10 times.. tried doing minor adjustments to the OPDA to try and get it to go away.. no luck.

Happens after about 160 degrees, and goes into limp mode just after 3k RPMs. Otherwise, seems to drive fine.

Going to call around to the stealerships tomorrow to see if I can find a new sensor.

Unfortunately, my brother in-law who also has an '05 LJ is out of town with his Jeep so I can't steal his to test.

(Fortunately he won't signup for forums, so he'll never know that I'd do such a thing. )

I've got a thread here about my OPDA woes and also I'm not an expert just try to read, listen and understand. Here is what I have gathered.

My understanding is that the dealer or someone with a Chrysler scanner needs to set the OPDA. I was able to move mine around and find a spot where the engine ran fine, at least didn't throw codes for the test ride.

But... I was told that the computer coordinates the fuel-air mixture based on the OPDA's data. That would mean for the engine to run right, beyond our seat of the pants assessment, you need to get the scan done.

Which OPDA did you go with? I put in the crown, used the sensor it came with and I have had zero issues. I tossed the factory sensor in the toolbox that stays in the jeep based on statements made by others, but the Crown sensor is running strong. I am curious if you bought the Dorman.
