check engine light after installing 95GT MAF

[mob]

I just finished cutting the flange off my 95GT MAF and I hooked everything back up, made sure everything was real tight so there was no leaks. When I start my car it surges real bad from about 600 to 1200rpm and about 2 seconds later I get a check engine light that stays on. And I cant check what the code is because every time I jump the eec with a wire and turn the key the check engine light just blinks once and doesn't do anything. Im pretty pissed that every time I do something my car never likes it. I could change a head light in my car and it wont run for days.

Put the old MAF and air duct back on and see if it still does weird things.

Gotta run to work but I will try that later thanks Joe.

If my stock one works, does that mean its probably the sensor thats bad? Its the -AA sensor.

Yes, unless you have some twisty turns in the intake ducts.

Remember that the sensors are not interchangeable between different types of housings.
The 94-95 Mustang 5.0 MAF & sensor is also found on:
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,
Evidently the –A1A, -A2A, AA, etc. on the end of the part number is a minor variant that did not change the operating specs. You should be able to ignore it and have everything work good.

Well I am using the stock air box right now. I got the MAF from my work. If I defect out the sensor, can a I put the new sensor back in the other housing I got? I cut off the flanges so I want to just swap out sensors not the whole thing. Itll be a 95 sensor going in a 95 housing, or is each sensor made for each specific housing?

As long as the housing is the same type or has the same part number, you can put a replacement sernsor on an old housing.

Thank you sir.
