i bought a 88 gt 5 speed not too long ago and just found out it had a pro m maf calibrated to 24#.I believe i have the stock 19# (the yellow tops).My question is will this cause problems? Should i put the stock one on? The idle isn't the best.

i would just go ahead and throw the #24 injectors on there but thats me! check into the prices of a #19 calibrated maf and #24 injectors. if you get the #19 calibrated maf sell the 24 make a couple bucks! hope that helps

i will at some point get the 24# injectors but wanted to know for now should i put the stock maf in? Will this cause problems leaving it as is?

Yes it will cause problems...

Run the stock MAF until you need to upgrade to 24's.

Do a search for converting a Fox 5.0 to run the MAF meter from a 94-95 Mustang.
Other than the adapter that you may need, it is a simple conversion to a 70mm housing.

i just swapped it out and now the check engine light is on.when i put the 24# back in the check engine light turned off.I didn't disconnect the battery during the swap should i have done so?

pull your ECM out, tell us the catch code, and look to make sure it doesnt have a chip

you will also want to disconnect the battery and reset the ECM

yellow tops are NOT 19s... theyd be orange

anrtman

sorry they are a little faded they might have been orange but they are more yellow then orange now

dimebag

ok well yellow is something but i forget what it is

and i have some old *** injectors, their obviously orange... im just sayin

im told yellows are 15lbers...

if they are yellow and yellow means 15lb's like dimebag said go find the dude that sold you the car, kick him in the nuts, and ask him why the hell he put 15 pound injectors on a mustang. Other than that i think they already answered your question.
