My mass air sensor is bad and was wondering what mafs i can use or does it have to be from a 95.
What size tb is stock and what size injectors.
My motor has a edrlbrock rolling thunder cam, shorty headers with no cats or mufflers.i want it to run as close to best with out a tune for now.
Was thinking about maybe mustang 19 or 24lb injectors, explorer 65mm tb and if a stang mafs caled for the 19s or 24s would work.

 

Are you sure it's not just the cam that's making the motor run bad.


Stock injectors are 19lb and the stock TB is a dual 52mm which is equal to a single 72mm.


.

 

Ok so id be better to keep stock tb and intake.was thinking about swapping to gt-40/explorer style intake.
Mafs is bad.i check for 12v at the live and both grounds and was good.the signal wire showed nothing

 

That would be a downgrade.

Signal wire should be at zero unless the engine was running. Are you also getting codes for the MAF?
If you do have to replace the meter then one from a 5.0 or 5.8 truck would be the best.

 

Signal wire remained at zero even with truck at idle and rpm raising slow and fast.
Is the 5.8 maf the same as the 5.0.the 5.8 isnt bigger in dia. And its calibrated for the same as the 5.0 maf?

 

Both trucks use the same MAF and injectors, and MAF meters aren't calibrated the computer is... those companies that sell "calibrated" MAF meters are lying to you.

 

You will have a better top end with the explorer intake, but loose tq power...Im going Holley Systemax on mine

 

The dyno results I have seen contradict that, the Explorer intake produces more low to midrange torque than all the others including the Holley which interestingly is heavily based on the 5.0 truck intake.

 

If you have a 351, the systemax intake is a great upgrade. If you have a 302/5.0 then the systemax lower is nearly identical to the stock truck lower.

The explorer intake is a good upgrade for a car or a lower reving engine. But there are plenty of better choices if you're willing to spend the money.

 

Oh, and if your maf is bad, you don't need to swap the whole meter, just swap the electronic piece on the top, no "calibration" required.
