Mass Air Sensor
So still haven't found my power problem. (Loss of power after 2K RPM)
I have ruled out my cats because the problem comes and goes...in a matter of seconds. I accelerate hard and it pulls, then it just laggs then it pulls.
I think it might be my fuel pump but when I run it hard it doesn't get hot like it is running lean...but I'm not ruling this out yet.
Someone told me that it could be my Mass Air Sensor. So I have been looking all over and cannot find the sensor to replace it.
I want to purchase an aftermarket Mass Air Meter (like C&L) but does that come with a new sensor? It looks like I bolt my old one to the meter.
Where can I find a new sensor? And what do they run in price?

RE: Mass Air Sensor
Hell dude just run down to your local home depot or lowes and buy yourself a length of 3" PVC pipe, cut it to the length of your stock meter, drill a hole big enough fit the meter element through, slap that bitch in there and poof you have a bigger maf meter. Will it work? Of course it will, cuz the size of the meter housing dont matter, its all in the computer.

RE: Mass Air Sensor
Chitown- I hope I just didn't pick up on the sarcasm in your post, and that you were NOT being serious...
A C&L meter re-uses the factory MAS, and PMAS meters come with a new MAS which is specific to the tube that you buy.
If you are sticking with the 19lb injectors, then the 94-95 Mustang MAF is a great option. Here is a list of vehicles it can be sourced from, and some other details...
For your combo, a better option may be the MAF/MAS from a 94-95 Mustang.
This is a 70mm tube, which is a direct swap for an A9* computer, as long as the 19's are still in use.
Here is a list of some of the Factory uses for this meter...
94-95 Mustang 5.0
94-95 Mustang 3.8
94-95 Mustang Cobra 5.0
92-94 Crown Vic 4.6
but there may be others.
the important features are...
70mm tube diameter
part number 'F2VF' on the MAS (the little black sensor box)
This meter would be a mild performance upgrade, worth a couple (5-7)HP.
The only 'converting' required is an inlet tube adapter. I can't find a good link right now, but they are available.
If nothing else, some guys have simply cut the flange off the 70mm housing and slipped their inlet hose over the MAF (similar to the original setup).
If you can't find one of these meters...
The factory meter for the MAF Mustang 5.0 was a 55mm tube with a 'F1ZF' MAS.
This sensor was also available on...
88-93 Mustang 5.0
89-95 Taurus SHO 3.0
88-93 T-Bird 3.8
92-93 T-Bird 5.0

your cats could have hardened you can tap them to see if it sounds like a hard like biscuit is what we called it inside moving around this can cause your problem.....check your fuel pressure every stang should have a gauge

RE: Mass Air Sensor
Sarcasm? What reason would I have to be sarcastic? I was just passing alongoneof the latestbits of wisdom I learned right here in this very forum. I've been shown the error of my ways by those greater then myself. I've been foolish to think all these years that tuning is required, ever! I have been shown a new world where the size of your MAF doesnt matter and all you need to run bigger injectors is a calibrated MAF. A world where no one cares about things like idle quality and drivability, where fuel curves and timing curves are a thing of the past and all you need to do is crank your distributor and bump your base timing up and all is right with the planet. Someone needs to call SCT, Diablo, TwEECer, PMS, and all the rest and tell them that all thier yearsof R&D andmillions of dollarsspent developing tuning sofware andequipment was a waste. All you need to do to tune your carbuy a huge calibrated MAF and and then twist and turn it till you find a spot were it doesnt die out at idle crank your distributor and your allgood. Sarcasm? Who me? Never.

Don't forget to recommend a AFPR too...
'Tuning' without that is just pointless
