junknotch

Hello new to this forum and need some advice. This is my second stang had a 88 notch before and now bought a 91 notch. The car runs like crap ( of course when i looked at it before I bought it it ran well ) The car can not get out of its own way. I changed the plugs wires cap fuel filter played with the timing. The car also runs rough on a idle when it warms up and dies at lights. The car has underdrive pulleys and I know the the amps usually run low at a idle but they dont kick up while the car is driven. ( my 88 would drop down and shoot right up) I made sure the firing order is correct, there are no leaks. I dont know if the maf is bad how do you test it ? or this motor is just tired and help would be great !!

Also looking for a clean trunk lid and front fenders must be clean !

thanks
Joe

you check fuel pressure? fuel pump might be going out.
your cats might be clogged also.
sounds like alternator might be going bad if volts dont come back up
under accleration, low voltage would also cause problems.

Check Codes to see if the MAF, or any other sensor, is bad. also i would recommend checking all of your grounds (you should also read this About Grounds)

The battery died on me last night cause it has a electric fan that runs off a basic on off switch and i forgot to shut it down. I charged the battery for a good time today cause the car would not hold a jump last night. It would die and could not restart. Now after charging the battery the amp gauge went right to the middle until I turned the lights on and fan then the car ran like sh*t. I am wondering if the alternator is junk and the car was running off the battery before. Any ideas would be great

r.barn

low voltage would cause all kinds problems.

if battery is old and was drained completely you may need a new one.
most auto parts stores will test both your battery and alternator for free.

check all your plug wires for cracks/burns

test the alt, i am betting it needs replaced

try cleaning the t/b and the maf, this could be the cause to the acceleration and idle problem also...
