Question Answered: Idles high in park and neutral, no service engine light when key is turned, ABS light
August 24, 2010, 04:03 PM
I would think you have a vacuum leak, that would account for the high idle in park and neutral, as well as the shifting hard into park and reverse. Vac routing problems and leaks are extremely common after an engine replacement, as are ground/wiring problems.
The proper method for removing the engine and transaxle in that vehicle is to remove from the bottom with the cradle. The front wheel ABS speed sensors have long harnesses that are run along and attached to the control arm. It is possible that the wiring was damaged there.

Would need more info here. What temperatures are deemed hot out? And what temps are deemed cold? How does the vehicle react when started cold and run till the engine is hot?
On Fords we run through self tests to see if the control module finds anything itself. I'd want to look at several different data pids like coolant temp readings, oxygen sensor readings, fuel trims, misfires etc.
There are plenty of instances when the coolant temp sensor says the coolant temp is 20 degrees when it's really 100 degrees, in this case the ecm will over fuel the vehicle.
There are other instances where certain intake gaskets leak air into the engine when under certain temp ranges and won't under other temp ranges.
Then again Ford ignition modules (for spark control) are very sensitive to heat when their damaged.
I recommend leaving at a trusted shop overnight so they can check everything over with it "cold out" and then again later when it's "hot out"
Question Answered: airbag light
August 24, 2010, 03:47 PM
Probably a long shot but is your car still under factory warranty by mileage? If so it may be a free repair.
The airbag light is on because the srs module has detected a problem somewhere in the srs system (supplemental restraint system). It includes crash sensors, control module, airbags themselves, seat belt pretensioners, any active head restraint system, etc.
The most common srs failure is the "clock spring" located inside the steering column. This is a taped wheel mechanism that allows wires to stay connected to the steering wheel. The electronics that run through the "clock spring" are for the drivers side airbag, the horn, and any cruise control or radio controls mounted on the steering wheel.
When this "clock spring" breaks, it may interrupt communication between the drivers side airbag and the srs module. Try and see if the horn, cruise control and radio controls work before bringing the car in for diagnosis. If anything there does not work make sure you tell your shop in hopes to keep the diagnostic part down some.
SRS repairs are usually costly, expensive on cars today is relative though.
Best of luck!
Question Answered: What is the towing capacity
August 24, 2010, 05:46 AM
Mitsubishi says the towing capacity is 2300 lbs. That is the total trailer and load weight.
Keep in mind the vehicle's curb weight empty is 3510 lbs, the gross vehicle weight rating (GVW) is 4730 lbs. This allows for 1220 lbs weight load on the Montero.
Any trailer will have a "tongue load". This is the downward weight placed on the tow vehicle by the trailer when the two are connected. As a general rule a trailer will transfer 10% of it's total weight onto the tongue. This weight needs to be considered in GVW.
Something like this: load capacity is about 1220 lbs. towing capacity is 2300 lbs. if the full tow capacity is used then 230 lbs is added to vehicle load leaving only 990 lbs for driver/passengers/gear in the Montero itself.
Question Answered: electrical problems
August 24, 2010, 05:26 AM
It may be an intermittent wiring problem in the door or harness going into the door, though this would also cause problems with the window going down.
More likely a problem with the window motor itself, or the regulator is worn causing window to go down too far, past it's designed stop.
Sometimes the felt or rubber "run" channel that the window rides in swells or becomes damaged causing extra friction, which in turn causes the motor to work harder to raise the window. The electrical system utilizes a circuit breaker so if the electrical load becomes too heavy or hot, the breaker trips causing no window operation at all for a few moments.
In the run channel scenario the problem may come and go based on weather conditions such as temperature or rain.
Best of Luck
Question Answered: what does code P0420 mean?
August 19, 2010, 12:30 PM
The code description is "catalyst efficiency below threshold", what this means is the tested efficiency of the catalytic converter (bank 1) is not sufficient. This may mean the catalytic converter is no good, it may mean that there is a sensor problem, possible wiring issue, computer may need software update, and it may mean that the converter has been contaminated internally. You will need it tested to be sure. Make sure you see an ASE master tech, most places simply replace that converter and sensor. This is a costly repair.
Question Answered: abs light and brake light on
August 19, 2010, 07:21 AM
Will need more information here. It means you have a problem with the ABS system, the system will set trouble codes to aid in determining the route cause. If the brakes feel normal I would suggest immediately checking fluid level in the master cylinder. If fluid is too low then it is leaking out, this is very dangerous and should not be driven until repaired. If everything appears normal then the issue is less severe but still needs to be evaluated thoroughly and repaired.
Question Answered: changing spark plugs?
August 19, 2010, 06:41 AM
You will need to remove the plastic intake cover (4 screws) and plastic ignition coil cover (2 screws and oil cap). This exposes the ignition coils. Unplug and remove all coils and the spark plugs are underneath. Once plugs are removed they should be inspected for deposits and fouling.
Make sure you use the proper plug for the vehicle, saving money on cheaper plugs will cost more in the long run. The spark plug gap on the new plug should be 1.0 - 1.1 mm
