First step would be to get the codes read to see what kind of problem you’re dealing with. Most auto parts store will provide a free reading.
Here are 3 diagnostic ideas you could try with Sea Foam to help figure it out:
- One thing you can do is add half a can of High Mileage Motor Treatment to the oil and see if the oil pressure improves. Oil screens on Chevys with active fuel management have a tendency to gum up and cause low pressure readings.
- Intake treatment with Sea Foam Spray. Dirty intake valves can cause low compression.
- Add a couple cans of High Mileage Motor Treatment to a low tank of fuel. This will help to amplify the intake cleaning.
