Engine Mechanical problem
2001 Mitsubishi Montero 6 cyl Two Wheel Drive Automatic 148000 miles
Hi, hopefully you can help me with this. I have a Montero Sport 2001 with 148k,
I would drive the car normal for like 30 minutes then I would park the car all fine, then after 10 minutes I try to start it, the car turns on but after 3 seconds it shuts off, if I keep a foot on the accelerator the car will remain on but as soonest I release the gas it will shut down, so I have to wait for it to cool down then it will work normal, that started happening 2 weeks ago now the car has a new symptom, If I'm driving over 40 mph and I stop maybe for a traffic light or an stop sign the car would shut down, then I would put the car in park so I can start it and it starts right up with no apparent problem.
I took the car with a mechanic and he has no idea what could be, I bought an expensive additive to clean the fuel system and it did not worked.
Carbon and coking build up could be the problem if not Have it tested,remove the unit, with the wires connected turn the key to the "on" position without starting the engine, it should move in or out.
Get back with what you have found so we can continue.

I took the idle motor off and tested it and it did move outwards, and it was really dirty, I cleaned the unit and the housing really good with break pad cleaner (spray) and a towel then I let it dry for 3 hours (just to make sure no chemicals were left behind) I put everything back in place and MAGIC the car turned right on, I couldn't wait to go and test the car at stop signs, going really fast and fully stopping and the engine really quiet stayed on AT ALL TIMES.
Thank you so much something so simple drove me insane, God Bless
