Rough Idle / stall and O2 heater error after tuneup
Hey everyone. I hope you all can help me figure out what is going on.
I have a 98 Durango SLT with a 5.9 engine.
I did a tuneup with Champion copper core spark plugs.
I as well replaced the cap and rotor with OEM from the dealership.
After doing the tuneup the engine now has a rough idle and stalls.
I have replaced all the sensors on the intake. ( MAF, TPS, IAC)
I even went as far as replacing the o2 sensors just in case.
Any suggestions on how to fix this?

Verify firing order is correct, and plugs are all gapped right.

Make sure everything is getting a good connection as well. (plug wires snapped on, etc.)

Aftermarket sensor can sometimes annoy the pcm, and it just won't run right.
