You should have the computer scanned for any stored diagnostic codes for the engine idle or transmission that may be causing the stalling. When going into reverse the transmission is at highest pressures and loads on the engine. If idle...

A scan tool can be used to see if the shifts (1-2, etc.) are being commanded. If you find they are being commanded, that is an indication that the "computer" part is working and so you would look at possibilities...

This may be potentially a faulty starter relay or starter relay fuse. I would start by checking the fuse in the fuse box for the starter relay (should be a 40 amp fuse). I would also recommend checking the alternator...

This engine has problems with the intake manifold and cylinder heads that will leak over time from the metal deterioration in the coolant passages, eventually causing it to leak either at the corners of the intake and heads or into...

The speedometer gets the vehicle's speed from the transmission. There are two speed sensors used to control shifting. Input speed and output speed. The output speed sensor is used for the speedometer. If it malfunctions, it will store a trouble...

This may be a result of a dirty or failing idle air control valve. The idle air control valve reads the air intake as it is mixed with fuel prior to being injected into the engine at low speeds and...

This may be a sign of a failing idle air control valve. The idle air control valve monitors the air intake as it is mixed with fuel prior to being injected into the engine. This valve is controlled by the...
