Odd question, I know...
This weekend I was finally give my truck a good washing. I cleaned
out the the gas cap area, and lightly hozed it out.
The truck ran fine all day yesterday, granted I didn't drive all
Yesterday, my truck was running on the crappy side, and threw a fit
when trying to back into a friends driveway. It kept wanting to
stall, and would drop RPM's to about 250 or so. (Yeah, two hundred
and fifty). It would rev fine in neutral or park, but when you let
off the throttle, the rpm's would bounce from 500 to 250.
My first thought is that I got some water in the gas.
The truck is an '04 Silverado SS.
