What MAF do u have.

you know, as of lately, some msd boxes have been failing and giving the same signs... people just unplug it and it seems to work fine, might want to try that out

do you have a bigger fuel pump?

maybe it just needs a tune (assuming it hadn't had one yet)

Try bypassing the MSD, then check the MAF. How are you tuning it? Maybe try a twEECer or Anderson PMS. Good luck!

sounds a bit like my problem. my car idels, and even drives real good at part throttle, but when you floor it, it does what you descibe. i had it at kauffmans. they put it on a computer system (looked similar to a tweecer) and found out its the MAF... not working at all.

do any of your friends local have a tweecer system that they can hook up your MAF to and see if its working correctly?

N8Miller, it actually was a Race Data systems data logger for 95 and older mustangs
