HELP me please.
story: bought a 1993 jeep grand cherokee with 173k on it. i have persisting problems. not sure if these are related?
symptoms: hard starting, excessive cranking rough idle, intermittent stall P to D or R rough running attempting to pass on highway
my mistakes:
173k replaced fuel pressure regulator and fuel pump (ouch) replaced spark plugs because some nut put bosch quadfires in it. immediately improved the hard starting problems.183k replaced intake gasket for suspected vacuum leak. no improvement. replaced spark plug wires. no improvement. replaced IAC, no improvement. replaced crank position sensor connector, after which i promptly broke the sensor, and replaced that too. no improvement.
tested and found to be ok: tps, map, ect, iat, alternator, vacuum, coil.
ready to load the .45 i'm losing my mind here. not sure if i should shoot myself, or the truck.
