NEED HELP!!!!!

[Dave93GT]

I’m having issues with my 93 gt, I recently had an e303 cam, new lifters, timing chain, afr heads, edelbrock performer efi intake installed on my car and ever since it doesn’t run right. Sometimes I have to keep patting the gas to keep it running or other times it runs but is running super rich. Im trying to figure out how to fix this but im so aggravated with it that it’s about to be for sale. Any advice would be very much appreciated

Did you do an maf and/or throttle body at the same time?

This says someone other than you installed these parts?
Did it run good for a time after the modifications?
Did it run good before the modifications?

I don't think the man set idle and/or timing properly. Nice parts though. I'm watching the market for an AFR headed 93 GT ;-)... can never have too many foxbodies.
