Possibly a bad catalytic converter.

Fuel filter?

Air filter?

Throttle body sensor? If it has one.

A '90? Due for wires/plugs/etc if you haven't already, and probably an injector cleaning if it has injectors.

vacuum leak in a 10 year old hose

Yeah, the wires got me on my old truck for about a year.

:howdy: Thanks for all the replies when i figure it out I will let you know

Fuel pump pressure. Check to see if there is a high and low pressure one.
Good luck.
Same problem on an '88 Ford. Took forever, found it eventually.

Well, after three weeks of being jerked around and finding that where I had the car I am starting to wondering if they really really tried and yes I was told they did. But I also drew the line the other day and got the car back. Broken still having the same problems and then some other issues yet to boot Brake problems. Yes I know it sounds like I don't take care of my car But I do Tune up last year, wires plugs etc, Fuel pump crap out the year before I put that in as well, Three years before that a Transmission had some do that one plus rear brake calipers with it and now one of then are leaking. Brakes when then have needed air filter when dirty,fuel filter, when I did the fuel pump, Now supposedly they put a Crank sensor, throttle positioning sensor and a used ECM (Brain) in the car.
I drove the car to the next shop as long as you use a light foot on the gas pedal you can go up to 53 miles a hour(I have a digital speed read out) But if you have to goose it or put a load on the engine like going over the bridge it cuts out (which it did going over the bridge) Kicked in Neutral and started back up on over the hill I went THANK YOU LORD!!!!

Took it some where else for them to try to figure out what the hell is going on with this Buick already spent 500.00 on it.

:nomoney: Tech took quick assessment on the car found one loose plug wire but still not the problem . IT's like the rev limiter is screwed up or something more to come later

Electrical Short,

Took the new place two days to find it and many $$$$$$$$$$$$$$$$$$


:yahoo: :yahoo: Beats the heck out of a car payment

Interesting. Glad you found it.

But it reminds me of an old Mazda B2200 pickup I had. One day it just decided it wasn't going to idle anymore, ran fine but stalled as soon as you took your foot off the gas. After many days of troubleshooting, I found a wire on the carb rubbed bare underneath the air cleaner, shorted and blew a fuse. A bit of black tape and a new fuse was all it took.
