after a month on my new timing chain, cap, rotor, plugs and wires, my truck runs great! Right up until it doesn't.
Symptoms:
-miss at idle
-way down on power
-missing, backfiring, and overall crap running at part throttle
When this happens, I get 5 codes pop up according to the shop:
-faulty 02 sensor (right rear)
-converter efficiency right side
-faulty crank pos. Sensor
-CPS and cam correlation
-random miss
The converter efficiency I get, that one is one regularly because the cat is broken up inside. Haven't gutted it yet but I will.
Now, it runs fine, though. Only code is for the cat and I've been driving around all day.
Possible solutions?
My FIL had an Olds that behaved in a similar way because of bad grounds underneath the driver side carpet. That being the case, where would I look for ground blocks on this truck?
Alternately, what is the possible of these sensors failing intermittently?
Finally, would a bad fuel filter or pump cause this?
