f-150 turns off when put on reverse

it shakes when put on revers and sometimes it turns off. please help me, im going crazy.also when Im stopped it feels like it wants to accelerate by itself

You easily could have a vacuum leak. take it to a mechanic.

"I don't care how many thousands you spent on your system, if you put it into a car, it will sound like shit."

Could be a wacked Throttle Position sensor (replace). Or a clogged Air Intake Control solenoid (clean it) if surging & dieing when shifting into reverse & forward. If while idling, Vac sys. leak. Pick up a manual for your truck, maybe read it while your kickin back listening to your stereo (check out the remastered "Beatles Collection"). I also haven't heard too many cars w/ "great sound", and no P/U Trucks. This may sound strange but here goes: I like listening to my engine pulling a grade loaded w/ 40 bags of cement & towing a mixer w/ seemingly little effort. Maybe that's just me. Anyway, getting it scanned for stored Continuous Memory error codes could prove useful in narrowing down the prob. Pep Boy's will do it for free if your call & make an appointment.

thanks for the help guys. It was easily fixed for $125 bucks by a local mechanic.
