94 gt running like crap plz HELP!!!!!!!!!!!!!!

I can only imagine a proper tune would really help. Hopefully someone with alittle more experience will jump in and help you out. Id say stay with a tune though and go from there.

 

For some perspective. How long have you had the car and did this just start to happen?

 

fuel filter by any chance?

 

Assuming the MAF/injectors/ECU are good and matched.

I know the Foxes had issues with the MAF needing clocked in some s/c cases. I had a Procharger on my 86 and it would run right only in a certain clocked position.

But it could be a slew of stuff with so many mods. Not sure if you can just plug in a lightning MAF and 42# injectors and get a running car without any sort of tuning.

 

Yes the tune would fix that. .. I would stop trying to run it... injectors are over twice the size of the stock ones.. the maf doesn't match the calibration in the stock tune. .

 

i put my money on the maf

I think a mail order tune would be difficult with the mods you have. I'm sure it would at least be drivable with one but a custom dyno tune would be your best option imo.

When did it start giving you trouble? I wouldn't give up on the supercharger unless you just don't like it.

If you changed to a nitrous set up you would only need 24lb injectors with a wet kit. A dry kit would allow you to keep the 42lb injectors. Regardless you need a tune if you don't currently have one. The car will not run correctly with a lightning mass air that isn't tuned to its injectors. I would start with a code scanner and getting in touch with a shop to go over the issues and schedule a tune.

Definitely sounds like a issue with the mass air if its not tuned to your injectors. Check your timing and fuel pressure also.

[MENTION=8201]Addermk2[/MENTION] he might help

 

If you had the qh I could help you some with tuning it

 

If you don't have a tune, your problem is that 90mm LMAF's are NOT calibrated for 42# injectors. You can't just slap parts on and expect it to work. Who did you get your Moates chip from? Was it just a chip, or was it a Quarterhorse.

You need a maf calibrated for 42lb inj's.
