High guys, I'm new to the stang world. I just purchased a 1995 GT and already having issues! The car has a shudder in neutral and through all gears. It bogs down when cold and idles like has a cam in it. Its driving me nuts! I have replaced the MAF sensor, the IAC valve, plugs, wires, cap, rotor, and ignition coil. The only code is for MAF sensor voltage to high. I checked the wiring and I'm getting 12.1 volts to the MAF witch is good. I need HELP!!!!!!!!!!!

 

Holy cow it's a 20 year old car. It could be almost anything. What about PCV Valves? Throttle body? Engine mounts? Does it have a gasket leak? It could even be that the motor is just flat give out. Good luck with it.

 

Hmm... on a carb engine, bogging when cold usually equals too lean. (Unless its the complete opposite where the choke isn't opening and its loading up but it usually dies under that situation.) How do the plugs look? Too white (lean)?

As for O2 to MAF voltage I'm not totally informed. But I was going to ask if the MAF has been cleaned/replaced, how are the O2 sensors?

And of course, have you cleaned the throttle body? And is the fuel filter plugging?

Just taking a shot.

 

I wonder I'd had very similar problemms with my 07 , changed filter cleaned injectors plugs nothing😡 turned out after a lot more reading in was the sock on my fuel pump pick up , it was so friggen caked up . So I took it out cleaned it up put it back & I got like a 100 kilometer gain and problem disappeared . just another idea.

 

Jack up the horn button and put a new car under it.

 

Rob tell me you changed your blinker fluid ?

 

I put one of these in instead of the pcv hose and no more oil all over the throttle body sensor, it catches about 1 ounce a week

 

Plug & play

 

Heck yea, I change my blinker fluid and wiper oil once a week.

 

No need towhore up the Op's thread Eh.


How many miles are on the engine? Check connections, check for leaks would be a few suggestions and also what post #3 and #4 said

 

I had the same with my 07 went through it all turned out the fuel pump pickup or sock was caked. removed it & cleaned it and sweetness all over again

 

Hey guys thanks for your suggestions. I have sense replaced the throttle body. I found trash in the tank, so I replaced the gas tank and fuel pump and sock. I thought some trash might have got to the injectors so I replaced them to. The plugs are not showing a lean condition. I am totally lost.

 

what did the pickup look like on the fuel pump ? I tested all my in extort first & by right the filter should have stopped the crap. So it was my sock on my pump .

Glad you got it.

 

Just a shot in the dark but do you know if the previous owner put a different tune on the car? Could it be that you're running a stock setup with a tune that was intended to be run with a different hardware configuration? I'm just totally guessing here.

 

Cold it be a vacuum leak? Our 92 GT has the same problem. If you but either or brake cleaner on the limes and the car idles higher then the lime has a leak.

 

The sock did not look clogged to me but like I said I went ahead and replaced the pump, sock, and the hole tank; no luck. Does any one know where I can get a wiring diagram for the MAF sensor wiring, I am still getting the MAF sensor voltage to high code.
