Little bit of a background the car is a 04 cavalier lss with a 06 g6 3500. The motor, harness and pcm was previously swapped into a 99 sunfire. Motor, harness and trans was pulled from the sunfire where goodies were added. While it was in the sunfire it ran perfectly fine no code at all and used the 3500 cam sensor with 05 injectors/rail and 05 gagt bin file which was tuned of course. I'll give a list of what was changed below.
What was changed:
Upon getting it running right on first start was a 24x crank sensor code. Thought it was the wiring which all checked out clear to the pcm, pulses as it should at pcm and all that good stuff. Switched out the cam sensor for a new 05 gagt crank sensor since was using the 3500 one, switched 24x out for a new 05 gagt sensor. Same code and same problem.
Did some testing again and with the 24x sensor the knock sensor will not work at all. Sets on 0 degrees of retard no matter what I raised the timing to. Unplugged cam sensor and knock sensor worked and the 24x sensor code disappeared. Which leads me to believe either using the wrong cam sensor, being the cam is ground with 1 degree of advance the cam lobe is also at that spec throwing the relation off between the crank sensor. Or really I have no idea but hard to tune it with the issue. So looking for thoughts as to the issue but did check the crank sensor ring and it also looks fine to me.
What was changed:
- Wot-tech little thumper cam
- Arp head studs
- 99 below cyro-treated timing set
- Comp Cam Drop in valve springs (Would have to look to see which)
- 36lb gtp injectors
