you took the carb off? explain...

TOOK IT OFF AND CLEANED THE GUNK THAT WAS ON IT THEN RESTILLED

how many miles so you have? Maybe just changing the plugs might help even if they looked good when you checked them out

about 141800

i think he meant Throtle body.
id check fuel pressure regulator too.

ok yes i ment throttle body lol i well check the fuel reg tommorow

actually i just re-read your post, and saw how many miles you have, it would also be a good idea to check for clogged fuel filter

might need new plugs if they have a lot of miles on them

at that many miles though on the car, it could be a lot of things

It would be very helpful if you could get your error codes read.
