The car dies when i backup

SOURCE: 91 camry starts and shuts off when put in drive or reverse

I was an ASE master auto tech for 13yrs and have seen this problem before. It sounds like the idle air control valve on the intake manifold has stopped working and the idle speed is not being controlled(letting the engine idle too slow which causes a stall when put under a load such as putting it in gear). Try giving it a little throttle while putting it in gear if that works let off the throttle if it dies you will know the Idle Air controll is not working.

it may be a brake light switch. on most vehicle the brake light switch releases the shift lock that may be your problem

I would suspect a vacuum leak. At idle under high vacuum the air fuel mix is being leaned out until you have misfiring so bad the engine quits. The exhaust smells rich because even a lean mixture, if it doesn't light off, if full of unburned fuel. At road speeds, the vacuum is low so the engine doesn't care if there is a small leak somewhere. It is getting most of its air through the open throttle. Check all your vacuum lines but remember that even if every line is okay, it could still be leaking from an old cracked intake manifold gasket.

I would suggest hat you replace the timing belt. The noise that you hear is the belt.

The O/D off means your overdrive is off. Have you accidently bumped it? It could be the start of a problem with electrical system. Usually a bad ground on your O/D may cause this. Intermitten problems are the hardest to track down and fix. Do you know what overdrive does? It's a gas savings device which cuts the engine's RPM's down by something like 1/3, like a 5th gear. That's why you are experiencing the jerking on the highway. Do you have an owners manual? If not a good place to look for one is at a local salvage yard, or online even. There may be something in there to explain this to you a little better than I did. I had a frien who had a simular problem. It turned out to be a bad fuse. It wasn't blown, it was broken, and it's element would jiggle around when he would hit bumps in the road. I don't know if this helped you, but it will give you place to start looking.
