Well, I'm glad we could help, and I hope it solves your problems. I know it sucks to not know if you can depend on your car. I tried running the dog out of mine to make the problem occur again and had absolutely no luck. I let it idle for ever, ran it hard, ran it slow, ran it long...not a stumble. It took that long haul of highway driving for mine to crap out.
Anyway, so far so good on my car. I'll find out for sure probably tomorrow when I head back up to Amarillo.
I've still got the old pump as a reminder...and the thing rattles. Kinda like there's a tiny little ball bearing shaking around in there. Are they suppose to do that??
Chris and everyone else (except for John...well, ok. John, you too), thanks for letting me bounce ideas off your skulls. Hope we got it licked.
