ok so here is my dilemma I have an 87 mustang hatchback gt with a built motor that is part of the problem. I was told it ia a 347 stroker. that's wat I was told. I know it has afr aluminum heads bbk 70mm throttle body and spacer eldebrock intake and bbk long tube headers and roller rockers 1.7 and c&l cold air tube. my issue is I am getting back fire and loss of power on acceleration. I have changed the plugs wires cap rotor and egr valve and coolant temp sensor. still have this issue was told I need mass air sensor but he did know which one to put on since he did not know cam size and exact injector size. so I'm looking for some suggestions we do know it is not the oem maf. my injectors are blue on top and black on bottom.... so which maf do I need and or what do u suggest is next. guy that worked on my car says from wat he can see build was done right but they may have lacked on the small details. o and the factory computer has been removed and aftermarket is in place where battery was and batt has been relocated to trunk.

What color are the injectors?

JOREUT8488

the injectors look to be a light blue on top with a black base

They look like these? bosch 24lb fuel injector

JOREUT8488

yes so those are the 24lb injectors so from wat I have been reading with my build I needed those injectors now the issue is the maf... the one that is in it is between a spectrum air cone and the c&l air intake tube... but the top of the plastic sensor is busted and gone.... so I cannot tell what it is.... where can I get just a replacement sensor and not the whole mass airflow meter housing?

So you have a stock MAF sensor with a sample tube for 24lb injectors or is the sensor mounted in stock maf housing? Logic tells me that the MAF is stock and that when the car was dyno tuned they calculated MAF data points to allow for the larger injectors.
Id like to see a picture of you current MAF sensor setup.

I'm new to this forum thing so I'm not sure how to show a pic... sorry I'm not tech savoy.
it is not stock it is in new housing the guy I had working on it tried to put stock maf in and it was not right

Have you checked timing and other basic things? Backfiring can be a symptom of many different problems. As for the maf C&L has a chart on their website for matching housings, tubes and injectors.

so I believe I have the correct tube size for the injectors I jus need to know if I am able to mount a stock sensor on the aftermarket housing and my car run correctly

here in my motor... u can see the duct tape on the sensor bc it has no plastic ion the top half.
