2003 Gmc Envoy 4.2 Ckp/Cmp Waveform
I need ckp/ cmp / ignition correlation .
Hi Gilerto In case you don't get what you're looking for, can I ask why you feel you need it? GM, even that vintage, is RICH is scan data and onboard diagnostics. I have diagnosed many faults on these as a GM dealer tech since the day these were new. BTW, you're more likely to get what you need for a Trailblazer. I don't think GMC sold as many Envoys as Chevrolet sold Trailblazers.
