"Service Engine Soon" Light

[lgalban]

On my 01 LS the engine just shuttered/misfiring, then the Service Engine Soon light came on. What causes this light to come and what to do?
It has 52k, I think it's under powertrain warranty till 60k
thanks, Larry :roll:

anything that raises the emission levels will cause that light to illuminate.

could be any of about 75 things.

Best bet is to go get the code pulled and then we can help you. Autozone will pull it for free.


Hey manybrews....only 75 things??? C'mon, man, you're a tech....you should at least be able to narrow it down to the top 50. :laughing:
