correct injector for fox body

Some ebay injectors are junk, I just swapped out a junk set for some 19's out of my engine.
How limited is the speed shops or machine shops in Columbia?
You may be able to send them off to get flow tested, or just buy new, 24lb injectors won't hurt you as long as you get a matching MAF.
Remember, do one step at a time, too many times too many things get changed and it makes repairing the problem harder.
Give us a pic of that engine, and the rest of the car too. Let's see what you got there.

WHat heads? I didn't see them listed. If stock, 19# should be plenty. 19# is the original injector size. Xcam is pretty aggressive with stock heads and in general for a street car.

Go through post #3 and start with dumping the codes. This is a 1980 bodied car with a 1989 engine? What wiring was used?

That MAF sensor is not correct for your application. It's an 95+ F150 5.0 MAF. It would cause your issues as the transfer curve is all wrong.


Can you take a picture of the electronics on top and the housing?

The correct, stock, 55mm MAF is part number:

E9ZF-12B579-AA, or F1ZZ-12B579-A

You can also run one of the below 70mm MAFS. These are the only part numbers you can use

1995-94 Mustang 3.8L F2VF-12B579-A2A,
1994-92 Crown Victoria 4.6L F2VF-12B579-A2A,
1995-94 Mustang, Mustang Cobra 5.0L F2VF-12B579-A2A,
1994-92 Town Car 4.6L F2VF-12B579-A2A,
1994-92 Grand Marquis 4.6L F2VF-12B579-A2A,


Those are all bolt-on flange style MAF's. You can either buy an adapter off Ebay for $10 to use with the stock airbox, or buy a 91-93 T-bird/Cougar MAF and use the housing only with the F2VF electronics listed above.

I understand if that might be a tad bit confusing
