Replace the fuel filter.

Not sayin that's your problem but dfurther diagnosis is difficult until you throw a filter into it.

i have seen these symptoms on other vehicles that ended up being T.P.S.

but as already stated: without having a "known-Good" fuel filter it will be hard

but a volt meter on your tps will be able to take readings at idle and w.o.t. to determine if it is operating within spec

i also suggest having the local muffler shop test your cat to see if it is clogged (i've also seen similar symptoms that turned out to be a seriously clogged cat)

yeah i tried the fuel filter thats not it but ill try the tps and cat thanks for the help
