I have an 88 Mustang Gt Vert, It's an AOD. And I was driving to school and when I was hitting bumps on the way to the car that car would like jump out of gear even if I was pressing the gas the car's rpm would go down under a 1,000 after hitting bumps. Then I get to school and turn and the car just stalls, I drive again to park and it kept stalling everytime I would put it in reverse or would try and turn the wheel. Could it be the alternator or anything else? Help needed

where does it usually idle at after warming up?

[SPATIK]

could be a loose connection somewhere or might just need the idle set up a little bit? maybe dodge the bumps.

a easy way to check for the alternator is to start your car then un hook your battery....if the car still runs then your alternator should be fine. could be alot of things doing this to your car......could be something in the mass air shorting out....it really could be alot of shit

I tested the alternator and its fine, the voltage is actually alot higher when the battery is disconnected, and the idle is fine. Mass air is out of the question, its speed density. This has been going on since it started to vibrate, so I gave it a complete tune up. And it still vibrates at idle and runs perfect at normal speed, when it gets to idle the voltage goes down alot..

how many miles on it.....could be something in the fuel system sounds like it could be starving for fuel at idel....you should talk a lil more.....maybe the injectors are cloged even the fuel filter.....

[ridebmxfbm]

changed fuel filter, 20,000 on motor I used fuel injector cleaner and it made a little difference, but i still dont know what it is

[White Thunder]

spark plugs and wires......or fuel....sounds like something isn't firing or getting fuel....im sure someone else will chime in with there thoughts

[ridebmxfbm]

spark plugs, spark plug wires, distributor cap, rotor, everything is all new just changed.. idk what it could be

when you rev it up past 2000 or 3000 rpm does it skip?

[ridebmxfbm]

no not at all, runs good only at idle does the voltage go down, and the car stalls at times when turning the wheel, also the bumps are big issue it only happens sometimes not always...

[White Thunder]

you don;t have UD pulleys do you..sounds like the alt to me now....

[ridebmxfbm]

no no UDP, but when I unhook the battery, the voltage level goes up at idle... instead of going down or dieing

[White Thunder]

something is pulling power away.....there is a thing as overcharging to...

[ridebmxfbm]

no the voltage never goes higher then the middle at WOT

[invisa stang]

there could be a bad connection going from the altinator

[White Thunder]

its something random...do you know how hard it is just to guess at whats wrong....

[invisa stang]

id have to be there when it does it to figure it out

[ridebmxfbm]

damn it sucks... thanks for trying though

[invisa stang]

has it done it latly?
