Fuel Problems...I think

[silver_pilate]

Thanks for all of the replies.

I replaced the TFI module last night. It was the original from the factory. Still had the green grease mark on the back 140,000 miles later. I figured it sure couldn't hurt anything to have a new one in.

Anyway, I'm going to take the car to Amarillo today through Saturday. About 90 miles of highway driving. If it's the EGR, maybe it will stick open, and if it the fuel pump relay, I've got a spare.

Chris, thanks for the explanations. I was curious as to why the EGR might cause the problem, and the other reasonings were helpful. If the car stalls out again, is there any way I can diagnose it as the EGR? Beat the crap out of it with a wrench and see if it pops shut? I assume plugging the vacuum line after the valve is already stuck would be a mute point and would only serve as a preventative measure?

As far as coming up with extra parts...after the rebuild I somehow ended up with a pair of extra cylinder heads, a cam, and an intake.
