Engine shut down? It has p1345 correlation code?

So, the correlation code is because the distributor is a tooth off, I would put the engine on top dead center and then remove the distributor and turn it one tooth to properly align the rotor to the cap. Check out the diagrams (below). Please let us know if you need anything else to get the problem fixed. The no communication problem you will need to start a new question for because we only handle one problem per thread.

Let me know what happens.

Have it TDC.

Okay, does the distributor line up with the images above. It even says if the distributor is off it will cause this code.

So, I did what you said matched up diagrams connected scanner to it. Still bucked and burnt com and came up?

Were they off before? Also do you have spark plugs wires cap and rotor? and if so are they AC Delco?

So here is where I am: I replaced ECM reset timing ran -2 for a bit. Now +24 also changed IAC, ICM, MAF, engine temperature. sensor. And pigtail to crank sensor plugs wires cap rotor. Once I changed pig tail truck runs rough until engine warms up. Then runs better than it ever has.

Okay, we are getting closer, can I ask if the engine has an exhaust leak before the primary O2 sensors? If so this can be the problem because it allows air to enter the system and fool the sensor.

No exhaust leaks. Cats are hollowed out cheated 02 sensors even has new 02 sensors in it.it will run + 21 24 degrees. On timing. tried relaxing crank sensor but fuel shut off wouldn't engage. Didn't before on old ECM either. Also, no codes.

Cheated the O2 sensors? is there a code for the cat inefficiency?

Used spark plug foulers to space out. No 02 codes.

Is the correlation code still present?

No.
