Hi there,

Your vehicle incorporates an on-board diagnostic (OBD) computer, which monitors behaviour of your vehicle's engine and ommission related cicruits.

This sounds like an electrical issue (I suspect perhaps your Throttle Position Sensor - TPS, or similar circuit). Your OBD computer will have stored the appropriate code/s causing this condition.

Have your codes read by an approved Mitsubishi Agent, who will then be able to advise what will be required to fix this issue.

Having your codes read should ALWAYS be the first step, as this will save you $'s and time, elimination the need to purchase unnecessary parts.

Hope this helps,

Scott

Have someone check your fuel presure, it may be time to replace your fuel pump. It worked for me.

Hello! You have symptoms that point to incorrect fuel pressure.
First have the fuel pressure tested as follows; #1...engine running at idle: 13- 20 psi. #2...key on engine off: 23-30 psi. If pressure is incorrect change the fuel pump.

Does the engine "surge" at idle? If so, check the "fuel injection pressure regulator idle air control valve". Apply a vacuum to it; If fuel flows it is not the problem.

I’m happy to help further over the phone at https://www.6ya.com/expert/david_6df67de3b14de867

fuel filter partly clogged. Remove and replace.

either fuel filter or fuel pump...replace filter since its cheaper. 6-12 dollars at autozone

Does it idle fine? Sounds like a vacuum leak.

as for the rattling sound have you checked the heat shield on the catalytic converter, mine was loose and was causing a rattling sound when it was at idle, and would go away as the rpm's increased.

It sounds like you may have a problem feeding the fuel to your engine, I had the same problem with my 89 RS. All the 1989 model's fuel systems were recalled. I think you may need a new fuel pump. The fuel pump is located inside the gas tank in the rear of the car right under the rear axle. The fuel pump itself isn't too expensive, but with other small parts such as the electrical harness upgrade and fuel filter and the labor you should be looking somewhere in the $500 range. I hope this helps.
