I have a 1995 mustang GT I'm am getting a few codes like mass air flow, air intake tempature sensor, I have the correct firing order,new spark plugs gaped at .052 and wires, fuel pressures good 40psi , I set timing to 10btdc and it bairly wants to stay running along with pooping/backfiring out of both intake and exhaust. When you do rev it up it almost has a stutter when reving, I've tried advancing timing to 14btdc and same thing. I know there's a little screw on throttle body to turn and adjust the idle rpm, as soon as I go below 1000rpm the motor shakes the whole car. I was told when I bought it that it does have a cam, I don't know what but don't think a cam would make it shake like that. Could a mass air flow cause that much trouble? And I replaced the air intake temp sensor I may need to reset codes to see if it fixed it.Any help would be appreciated, thanks
Unsure of motor parts I know it's a 95 5.0 HO other than that I don't know,was told it had a cam but you know how that goes. I have replaced the intake air sensor. I'm going to clear codes and check to see if it fixed it next day I'm off
Can you explain what the little screw is on the left side of the throttle body is that I thought controlled the idle cause it screws down and pushes on the throttle I just assumed that was what it does
i can try to get that screw back in the right position, Yea im going to test the MAF wensday when im off, and replace if i need too, Been like this ever since i got it. Wife loves Mustangs she seen it and feel in love with the look of it and here i am trying to get it running for her, lol
I was just asking I was looking at some ways to test the MAF online and some one had a video saying if you unplug the MAF while running it would cause the car to shut off. I was just asking if that was right or what was a way of testing if MAF was bad or is it pretty much if Code says the MAF is bad then its bad?
ok so i got it to running at 14deg btdc and i had to fiddle with the throttle stop screw and the IAC to get it running but it seems to run ok and idle at about 750-800rpm i know i have a MAF Code and Intake Air temp sensor code, I did change the Intake Air temp sensor so im hoping that solved that im fixing to check the MAF. Ill try to upload a video of it running later maybe yall can hear/see something i dont,which im sure you will,lol. Its not pretty not does she run pretty but its got good compression and i want to get her back to looking and running like it should.
I was trying to make a video more of it running thinking it might help. It doesn't seen to like 10 deg damn near chokes down. If it's a waste of time don't waste your finger muscles typeing... Simple as that. Wouldn't have posted if I didn't want help. Trying to learn here and figure out what's going on. I tried to say thanks for the help in last post and I'm going to get the MAF reading later tonight. Have to wait to next check anyways to get a new MAF if that's what it is.
Im going to get measurements later tonight if you would have read that. I made the video just for the sound to see if anyone heard anything out of the ordinary I hadnt. The timing crap was just to see if it would pickup and it didn't .Anyways Mods can close this thread now if they would like I am done posting here thanks for the help everyone.
