Heres the deal the car keeps throwin a P0300 mutiple cylinder misfire, i reset it, and it eventually comes back on. Ive replaced the plugs twice with NGK BPR7ES gapped to mitsu spec

Anyone have any idea on what the heck could be wrong, and if mitsu will cover it under warrenty? would any of the mods below be a problem? I also have a turbo timer

Any help would be great

 

SEARCH.

It's not your mods, it's the car. Don't fret there.

There's fixes for this from the dealership - although they don't always work.

 

i know the mods arent causing the problem i just wanna no if worst comes to worst and i need to take it to mitsu, if they will be a problem

 

it's probably your O2 sensor if you have an aftermarket exhaust. My CEL comes on sometimes, but eventually turns itself off once it resets. If not the O2, you had better go to the Stealership and void your warrenty........

 

Get a flash from Al he'll give you the latest mitsu P0300 code rom updates along with your flash not 100% garenteed but I think Al's had pretty good luck with it so far. PM him
