Bullitt seems like its dead up top...

[vteckiller2000]

I'm positive the pedal is to the floor, because its fine up until that rpm range. So as of right now im going to try and reset the eec, check the tps voltage, check the coils for cracks, check the fuel pressure, have the cel codes checked, and check for air leaks. Anything else to look for?

Change your fuel filter.

already did that, didn't help

What kind of plugs are in it, how long have they been in there?

 

[mg02bullitt]

I guess i was wrong, i used NGK v-power plugs, so hopefully theres nothing wrong with that kind. They've got probably 200 miles on them, if that.

Not sure then, I'd have to look at it.

my friends gt just had this problem...needed a new fuel filter

 

[mg02bullitt]

thats what i thought it was too, so i changed it and it didn't help at all, im starting to think its the fuel pump?

See what that MIL is before you start throwing anymore parts at it. TPS very seldom go bad on Ford's. The PCM wont pick up MAF and fuel problems a lot of the time though.

I would throw it on the dyno. Most place charge about $75 for three pulls. That'll get you a full read out on just about everything. Sounds to me like the car is getting lean on the topside. It used to be a v6 right? You did change out the ECU didn't you?

It wouldnt run at all without the right PCM.

Hmm, I would look at the fuel pressure and the COPs.

I think it may be a spark problem. Tends to show up more at higher rpms. I know an LT-1 TransAm has no where the same ignition, but when spark when bad it showed up at +4500 rpms (before the vented distributors). Maybe a bad coil-on-plug pack?

 

[mg02bullitt]

I'll definitely look at the COP's. Is there a common place they crack or anything? Or what exactly goes wrong with them?

very true about plugs, for some reason my car runs like crap really on any plugs besides NGK and factory

NGK TR6's ftw
