Hello all. My 07 GT pings a little during sudden acceleration. The car has no mods and the gas I use is 87 ocatne at the regular gas stations, not Shell, Chevron, or Union 76. Could it be cheap or low octane gas. I know these cars should run on 87 without problems. Have any of you had this problem? Thanks in advance. :confused:

How many miles you got it may be time for a new fuel filter.

These cars run rich with the factory tunes so it may be time to change your spark plugs as they may have a nice build up on them. Also change the fuel filter and clean the MAF sensor. All do a Seafoam treatment and maybe some fuel injector cleaning additive.
