cut out to idle or buck (at speed)

[dondarnell]

Car runs well most of the time under throttle, part or full. At cruise, it can cut out, but not consistently. Really only happens consistently on the highway.

I posted earlier, and some said it was the TPS. I replaced that with a new one, and following Clark's garage instructions, I am sure that I have it adjusted properly.

I have also checked the cap and wires, which are both pretty new. They still look pretty new.

Fuel filter is also new.

Any body have any ideas? I have a DE day this next tuesday.

How is the gas? Did your car sit for a while with a partially filled tank?

If so, I would suggest trying some fuel system dryer - an alcohol based fuel additive that absorbs the water in the gas tank and allows it to be burned off.

This is a low cost, easy solution and worth a try.

Yep - it sat for a looooog time. About two years. But I have put two treatments in so far. The problem seems to come and go, so that might be it. Thanks.
