What can I pull a MAF off of if there are no SC's available locally. I need it today. I have a 93SC 5-speed.


I am assuming my MAF is bad. The car has had a major idle issue and hasnt blown any codes or CEL. I took it off and cleaned it today and it didnt make any changes to the idle. I assume cleaning it messed it up because now the car will not start with it plugged in. I can unplug it, start the car and then re-plug it and there is no change. Any pointers. Thanks for the patience and help.

I changed the plugs and wires, cleaned the TB and though it runs better than it did with the Taylors and Irridium plugs. It still idles bad.

No not really, its not much better but it doesnt shake as much as it did.

Ok, since I cant figure out what stock replacement there is. Can I just purchase a C&L and replace mine. Will it work with the stock TB. The meter does not come with the electronics. How am I suppose to replace that as well?

if the maf is bad it will throw out a hard fault code... which wont let u run any test when it is bad.. happened to me... as for ur idle issues have u tried the iac valve?

The C&L uses your stock electronics so no

Any 5.0 mustang Mass air will work and they should be plenty easy to find

I dont understand, I have had four 86 Mustang GT's and the MAF were calibrated for 19# injectors. Does this mean I have to use a certain year. How would a MAF calibrated for 19# work in an SC calibrated for 30#'s

How would a MAF calibrated for 19# work in an SC calibrated for 30#'s....the 24# rated 'Stang GT mafs have the same flow rates as the 30# SC mafs...it's a direct swap..not sure which yrs they are but I'm sure that someone on here can tell you or check some of the 'Stang forums and you can most likely pick one up from there.

I may be mistaken because it has been awhile but, the mustand did not change injectors until 93. I could be wrong but pre 93 ran 19# and to convert to the 93 Cobra (70mm MAF) you needed to upgrade to the 24#. Its a shame, I truly love my SC more than any of the stangs I owned but the repairs and mainrenance is a bear compared to that of the stang. Thanks for the help

late 88 and up stangs up untill the 95 5.0's are calibrated the same. The mass air isnt whats calibrated to the injector size teh EEC is.

88-95 cobra, reg 5.0, v6 thunderbirds and stangs, 89-95 SC's and various other fords have mass airs that are interchangable regardless of factory injector size.

We have this discussion yearly and for some reason it never cathces on.

After wondering through the scrap yard yesterday I found numerous 70mm MAF on the mustands and T-bird LX's and some cougars but the part number on the senor itself was differant. Doesnt that matter or does it just have to be a 70 mm?

The part number doesn't matter. You only want the electronics off it anyways.

Trust DamonSlowpokeBaumann. See this thread http://www.sccoa.com/forums/showthread.php?t=49418&highlight=maf+electronics+mustang

BTW - if idle doesn't clean up after unplugging the MAF. Then the MAF wasn't your problem.
