Here is my 2 cents that fixed my Nagging issue of many months.

It ran rich and bogged down the longer I sat the worse it got and it would stubble from a light or any time I stopped.

Here was the Fix Broken wire from the ECU to the Temp 2 sensor. somtimes it had connection sometimes not. Check the wires and replace if needed

Other Issue Drive for awhile and it would run on all 4 cylinders great at start up as it warmed up and as I drove it, it felt as if went to 3 cylinders and a few
times only 2. A total Dog!! Took forever to find the issue. Come find out the Lifters were over chargeing and floating the valves so I would loose
compression and everything else. I rebuilt this motor but before doing so, when it ran on only 3 cyl I did a compression check and found a Dead Cyl.
Adjusted the valves to 0 lash and had excellent compression. Pulled and swapped the motor with one that needed a rebuild had low oil pressure. Pulled the
motor again and installed the rebuild with lifters and all and everything has been fine. other then the stupid oil leak at the oil pump. but I know how to fix it
next time I have to do a exhaust fix for now just a few drops on the floor here and there to remind me there is oil in it.

Good luck Jonce
