Ok, so this weekend I changed out my OPDA and everything seemed to go smoothly. It is an 03 Rubi for reference. I changed it out Saturday and drove a decent amount the rest of the day and on Sunday. Monday morning it ran fine but after a very slow (lots of snow and not 1 salt truck) 30 mile drive that took about 3 hours it started running kind of weird.
It almost sounds as if it is missing slightly, or firing order is off a bit, especially at higher RPMs above 3K.
Could this possibly be caused by the CPS being out of perfect alignment? I would rather track down another issue than spend $100 for the dealer to reset an already correctly set CPS.
A few things to note about the install - The new part was slightly larger than the hole it goes into so I ground it down slightly. My old man seems to believe this could cause an issue in the alignment of the OPDA drive gear and Cam gear, I don't agree as the mount is static in the oil pump and that should align it, and that my old one had a decent amount of play in the hole and on the shaft it self.
I am not throwing any codes for CPS alignment but did throw a P0420 catalyst code. I am almost 100% certain that has come up in the past quite often but I never wrote it down. The codes were cleared after I installed the new OPDA to be allerted if the code for misalignment popped up.
The last question, which I will ask in my thread about the OPDA as well, is when the dealer connects there programmer do they have to move the OPDA to get it right or do they simply reset the value of the OPDA in the computer? Reason I ask is because I used RTV instead of the paper gasket as I had that and not paper gasket material. And didn't know that the gasket doesn't come in the kit.
Any help is much appreciated guys, I'm just concerned I may blow this motor.
