2002 ford explorer 4.0 xls, shuts off when coming to a stop and also when switchin from drive to reverse. the engine also smokes at the exhaust manifold I'm guessing

Sounds like a possible idle air control problem (IAC) The smoke probably has nothing to do with the idle problem. Possible valve cover leak??

How do I reset my computer in my 1998 ford explorer 4ltr v6 it's idoling at 1100 rpm

First clean the idle air control valve with a non-chlronated brake cleaner and a wire brush or replace it then reset your computer by either using a scan tool,or pulling the ECM fuse out then put it back or take the ground cable off the battery for 30 seconds.The IAC Valve is whats causing it to idle high.

Whe you retrofitted the system to r134a ,did you subtract the amount from r12 to r134a. The system will hold less r134a than r12. It is roughly four oz less than r12.

Starter/solenoid prob?

Replace the MAF sensor. The starter is overheating due to cranking excessively. It has noyhing to do with the engine staying running. The MAF sensor is located as the first sensor out of air cleaner. It controls the fuel. Good luck and have a safe trip.
