On my 2001 Diamante, when I start it, I have to push the gas pedle to the floor and hold it there b4 the car will start. Could this be a gas filter or mass air flow sensor problem?


Firstly, try to avoid depressing the gas pedal if possible, as this will flood the injection system.

Due to the intricacy of your Diamante's Emission system, this condition could be caused by any number of air/fuel components.

For this reason, DO NOT replace any parts, until you have had your diagnostic codes checked.

If you're technically inclined, you can check the diagnostics yourself by jumping the No.1 & No. 4 pins on your diagnostic connector (under dash, above driver's knee). Turn key to ON (do not star) and observe the flash sequence on your Check Engine light.

Report back with your findings...

Due to the intricacy of your Diamante's Emission system, this condition could be caused by any number of Air/Fuel/Vaccuum components (or sensors).

For this reason, you should have your diagnostics checked.

In the meantime, look for any small vaccuum hoses which may have detached themselves from the MAP sensor, or other related component.

Good luck...

98 Mitsubishi 3000GT air conditioning does not blow cold

Could be a blockage. Get an air-con specialist to blow the lines out. Check for any leaks from the rubber pipes. The twisting nature of AC pipes in cars can perish and if you have heard a blow out (like a tire blowout) the air con might have blown through a pipe.

Any leaves trapped in the windshield/hood gutter?

Air conditioner blows hot air . gauge shows full .

It needs to be re-gassed. Take the car to an Auto Mechanic to get the Air-Conditioning re-gassed. They might also need to check it for leaks to make sure the gas stays in.
