What to do
- With the engine cold, compression on multiple cylinders may read 0 PSI (= 0 kPa).
- The engine may pop through the intake or exhaust while cranking, and the spark plugs may be fuel fouled.
- If there is valve damage or cam followers are out of place, make the mechanical repairs first, then perform the cleaning procedure to keep the concern from returning.
- With the engine at operating temperature, slowly induce a bottle of GM Upper Engine and Fuel Injection Cleaner with RPM held above idle so the engine does not stall (typically around 2,000 RPM).
- Turn the engine off and let the cleaner soak for 2.5 to 3 hours.
- To complete the repair, change the engine oil and filter.
