Chevrolet Camaro Pinging, Air Bag Light Q. Hello there, My name is Enrique, I'm from Monterey Mexico, I have been looking for some help for my 1998 Chevrolet Camaro. It's a 5.7 liter engine, automatic transmission, ABS, without cruise control and 43,500 miles, The problem appear only when the engine is in his normal temperature after 30 minutes started.

When I press the gas soft or hard it sounds a knock and then disappear is short and discontinuous. Some friend recommended to use an octane booster and I did it, but the problem is still there. A mechanic told me that probably the knock sensor need to be replaced but I really don't know what to do.

The other problem that I have also is the following, when I turn on the car some lights turn on also in the cluster panel, then everyone turns off except one that I think is the airbag indicator, I being worry about this red light. I was wondering if you can tell me when can I find information related for both problems. I hope you can help me with these issues. I'll be waiting for your response.

Thank you in advance...

A. Sounds like you are describing a "ping". This could be from an EGR valve not working, timing advanced too far or the engine running too hot.

If the airbag light is on there will be a code stored in the Supplemental Inflatable Restraint (SIR) module. You need to have it scanned for codes to find what problem is.
