If you had an issue before you did all that work to it then you will have an issue with the fitech system
I have followed your posts, you have to find and fix this popping thing

Dude there is no quick fix. You need to take the troubleshooting steps necessary to find the problem...

What kind of cap and rotor are on the distributor? A cheap cap will allow scatter spark. Use a Motorcraft or MSD cap.

If you are troubleshooting this on another thread maybe @karthief can merge them.

Pictures of the engine and parts I need detail in order to help you.


Bama tunes are junk. They are so bad I will give away the chip i bought years ago. Waste of money, want a Bama tune? Go bump the timing up 3*

That's the wrong train of thought if you have a tune in the ECU now remove the tune the stock ECU should run just fine with everything that you have installed. There are guys making over 600 horsepower with the stock ECU

There is a ground by the computer. I don't think you could of burnt the trace on your computer, but do you have a buddy with a spare computer to try?

You can also inspect the trace in yours to cut that out as well

If you had problems with it before and the computer being a constant....maybe but inspect to rule out.

Also grab a pic of your mass air sensor and the part number. Have you unplugged the mass air sensor to see if it runs any different?

Unplugged mass air and it almost died

That's normal it means it's working.

Take the cap off the distributor, look at the terminals that the rotor sends spark too...
Are they made of brass or aluminum? Is there any carbon tracking on the underside of the cap?

Not sure if that would cause the popping issue or not...

Maybe someone will chime in
