1999 Mitsubishi Diamante Reviews, Pricing & Specs

One day going to work car started shutting off and will only run decent at WOT?

I noticed my gas tank no longer pressurized or made the plunk sound the day after car starter running horrible. I changed plug, wires, distributor cap, fuel pump, fuel lines, fuel filter, and gas cap. Engine light has been on for years but not now when car hardly runs. When I press the gas in neutral 50% of the time it misses, bogs, or spits. In drive I have to feather the throttle to get it to go unless I floor it then it screams like a wild dog and hauls . So frustrating I love my old car had it 10+ yrs and it's my only transportation. Please please help me with this issue!!! I am very good at shade mechanic stuff. Just can't figure out what's the issue since there's no codes.

How difficult is it to get to the thermostat on this vehicle

I have a 99 mitsubitchi diamante I can't find coil springs for. What would be a similar replacement for front and rear.

Called dealer and they want 400 a pop to special order. Moog doesn't make any and I don't want to lower my car with these nyc potholes. If I can use the ones desighned for an 04 eclipse or a galant.

99 Mitsubishi diamante the car will run fine for a while (a couple of hours sometimes a day or two) then while driving it starts missing And rpms drop and acts like its gona die sometimes it does.
