plugs and wires have been replaced. Coil pack maybe?

THose are not my plugs, they were another posters. Yeah I need to check my fuel system

I really do appreciate the help guys, just trying to get this thing running good

im not sure what you mean by the difference of cutting out or breaking up. I think it may be a combination. as I can rev through it and at around 4500 it runs great. I have also noticed thst it does not do it every time which I think is weird. Got some premium fuel and injector cleaner in the car now so we will see if that helps. How would i check fuel pressure?

ANy ideas?

So replaced plug wires and plugs and in general the car seems to run better, but problem still exsists. Where the hell do I go now? Any ideas?

good question, i dont know. im thinking it may be a timing issue. how would i check that?

i bought belden premium spark plug wires and ngk plugs, gonna be installing them tonight. I dont know what is next after i install these

so could that be my problem?

It cleans up around 4500 rpm after stuttering at 4000 rpm. I think I'm going to do plugs and plug wires? Should I do them?

yeah works perfect

I ran the stock one for 6 months and just swapped out the ecu today cuz i got a smokin deal on one. anyway it breaks up at 4,000 but will keep reving than clears up at 4500. I dont undertand what u mean by the speedo and the VSS? please explain

UPDATE!!!! Im very determined to get this fixed as I Have trouble getting up steeper hills as it cuts out at 4000 rpm. The Im using the 2.5 intake manifold as well as throttle body/intake on the 2.2 motor. dont know if this makes a difference. So far this is what has been replaced- Fuel Filter ECU (replaced the 2.5 ecu with a 2.2 ecu) Knock Sensor any other ideas? Could it be the VSS wire? Again there is no CEL Please help!!

It does feel like it is hitting the rev limiter, however there is no CEL...

any help
