Re: LT-1 Pings

Have you tried the fuel filter, catalytic converters, o2 sensors? SES light usually has to do with emissions equip.
Hope you find it!

Whoa Nellie. STOP! Don't change parts. FIND the problem first and diagnose it, or you'll spend more in parts and repairs than the car could ever be worth :).
Pinging could be bad fuel, too low of an octane of fuel, bad brand of fuel (some do it worse than others), timing issues, or EGR problems.
I'd start with the fuel quality/brand selection FIRST and see where that nets you and then go from there.
