Just bought my GXP w/ six speed. It is starting to stall on me. Usually start then die, start, die. By the 3-4 time, it start with a little help from the gas pedal. Dirty fuel injectors? Fuel filter?

Sounds more like a fuel pump issue. How many miles are on it?

It has just under 60,000 miles. I am using lower octane fuel vs. the previous owner - 91 vs. the 93. Would it be helpful to run a few tanks of higher octane fuel?

F.Y.I. The fuel filter is inside the fuel pump assembly and, to the best of my knowledge, is only replaceable by changing the entire assembly. Yet another bright idea from the bean counting individuals at General Motors... a non-serviceable versus inline fuel filter...gesh.
