i have problem with my car,tryed to fix but still have same problem,computer ifcode is 300 and said misfire,please if somebody can help.

over here nobody knows anything about diamantes i guess. i have a lot of questions people review and leave no feedback. how shame. lol. i think try some other mitsubishi forums.

there are plenty of people that know about diamantes... however, with a generic question like that, no one is capable of helping.

a misfire code? That means the car was misfiring. Could be ignition (plugs, wires, cap, rotor). could be fuel (injector, harness, pcm, misc. sensors). Could be mechanical (low compression, damaged valve, etc.etc).
