Could also be carbon build up on the oxygen sensor. Buy a new gasket for it,take the cover off and clean any carbon off.

You can also check to see if you're getting 50psi on your VST. Grab a fuel pressure gauge from your local automotive shop and tap into the inspection outlet on top of the tank. The gauge should read a constant 50psi at all RPMs. If it's reads low, you could have a clog in the VST filter. If you've ran ethanol fuel through that engine, it builds up a white grime that clogs the little screen at the bottom of the tank. Try this if the O2 sensor isn't your culprit. |
