title says it all cps, tps, iac only a month or two old fuel filter brand new pulled fuel pump and all looks well, plugs are brand new, injectors are all working dont kno about clogged but i did run sea foam thru it and nothing different yet so im thinkin injectors need professionally cleaned or replaced, also thinking about the wire set the coil or the distributer, if you guys have any ideas or suggestions please let me kno asap

Have you looked at your cap and rotor?look inside and see if there is anything that could cause this,like corrosion,carbon tracks,etc. I have had problems with cap and rotor on mine when it gets old.
They are so cheap just replace them and see if it helps.

the cap and rotor are pretty new thats why im leaning more towards fuel issues, i had pulled the injectors a while back and just cleaned them with what i had and wiped them down and it seemed to help with the problem then so im thinkin professional cleaning will do it but ill check the cap and rotor too

Have you checked the pressure at idle with a guage?You may have a regulator problem.

claygrassmann

havent checked that either but thats pretty new too ill have to get a guage i been wanting one for a while now anyways

I always have looked at issues that come up as a reason to buy more tools,just seems like the right thing to do. The other thing it could be is the cam position sensor in the distibutor,it works together with the cps to maintain timing and injector timing,02 sensor adjusts injector pulse width.

i had a similar problem (sputter at 2000rpms and with accelorator to the floor would almost die out) but mine was due to over heating and gas tank had trash in it. electric fan wasn't coming on so I straight wired it , removed and cleaned gas tank, and installed new fuel pump filter sock and fuel filter on rail and hasn't done it since. don't know if that is what's wrong with yours just thought it was something you could look into

Could very well be a clogged catalytic converter as well.
