94 toyota camry has low idle and stalls when in reverse

I am chasing this problem also in my 94 Camry. I am investigating

- vacuum leak somewhere in the intake manifolding or hose
- EGR valve malfunction
- IAC valve malfunction
- deteriorated spark plug leads
- head gasket leak
- fuel pressure low from pump
- malfunctioning fuel pressure return or relief valve

Fuel filter,air filter,IAC sensor,Bring up low idle at throttle body is small set screw.

It can be low fuel pressure issue or clogged fuel pump. Or its engine related issues,---------------

Could be ignition or fuel related. Someone will have to figure out which to proceed.
Could be a relay or an ignition component. The stalling could also involve the idle air control valve.

may have auto choke issue's or throttel position sencer issue's.

Sometimes a low battery or dead one can erase idle parameters in the computer memory. Also for 2002 to 06 the electric throttle position sender at the top of the gas pedal is very slightly adjustable. Loosen the nut and see if there is enough slot there to bring your idle up a hair.

replace the 02 sensor or the egr valve in the intake manifold needs replace or cleanout and is carboned up

tighten idle screw on throttle body / carburetor...

start by pulling hose off egr valve see if idles smoother almost instantly
