Try checking the coil for leaks. if it looks discolored anywhere on the coils then it's leaking. i had the same problem with mine. sounds like the same thing mine was doing untill i replaced the coil. could also be the drive gear for the distributor to but highly unlikely

COMPUTER DISPLAYS A MAP SENSOR SHORT CIRCUIT COULD THE MAP SENSOR PREVENTING IT FROM STARTING. AFTER A FEW HOURS IT WILL START UP AGAIN BUT AFTER IT HEATS UP ITLL DO IT AGAIN..


Won't usually prevent from starting, but can. Definitely creates a number of driveability issues including hard starting, rough idle, stalling, buck/surge while driving, and poor fuel economy.

Transmission leak


Most likely problems described are not related. Rough idle and rough at low speeds could be caused by spark plug and wires due for replacement. Tranny pans known to leak and is an easy condition to remedy with filter and gasket replacement
