New List Participant - very new

[Scott Schaaf]

I am having the same problem,,, 'bout ready to change the TPS.    I dumped
a BUNCH of injector cleaner in the tank,, and the miss go MUCH better..  I
guess I must have some plugged infectors!!    The gas wars here in Ohio is
causing some REALLY SHI**Y gas!!
