Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello, when you used the starting fluid did it backfire thourgh the intake or out of the exhaust?
Thanks, ***** ***** could be going on here.
1. Timing chain may have worn and slipped.
2. Crank position sensor may be bad giving wrong reference
What I would suggest doing is a compression check to make sure the timing chain hasnt slipped. Compression should be above 100PSI on all cylinders and within 10% of each other.
Let me know what you find and we can work further if needed.
