Dealer said they think an injector locked up and caused the backfire. Also blew off the induction hose. They are in contact with Mit. to get permission to replace all injectors. Thanks for the quick replies, I am relieved it is not something worse.

 

Luckily still under warranty, everything covered!

 

lol your car probally had a really bad boost leak causing you to run rich enough to misfire. When you get your back from the dealer I suggest replacing all the clamps with tbolts.

 

That is the most rediculous thing i have ever heard.

Backfire into the intercooler pipe causing it to blow?

Oh well, hope you get a new set of injectors

 

And we all know, the dealer is the expert.

They are wasting their ****ing time and Mitsu's money on their goose chase.

Put your IC hose back on and get on the road.

 

ahhh come on, first they clean the injectors and now they decided it is best to replace them all, riighhttt!!!. What if you still get the misfire code....are they going to give you a new set of plugs, coils, starter....free oil change to keep your mouth shut...

 

Oh, he will! It's inevitable once you begin to get it.

 

The misfire code has been different lately. It started as a misfire at like 3700rpms. That was corrected with the reprogram. Now it has been misfiring at idle, and 0mph. They said they thought it was the injectors, but who knows at this point.

 

If you or your dealer can get this fixed, you will be the first to do so. You dealer can make a LOAD of money if they do. Good luck

FWIW, I get this P0300 code too just sitting at idle. There is no other symtom or drivability problem associated with this code on my car at all. Just a computer glitch I assume.

 

so do you just live with the service engine soon light on all the time? that really bothers me.

 

Yes. I learned to live with it.
But I also have something (ECU+ and PalmPilot) attached to the ODB port that I can read off it rather quickly.
If you don't want that SES light on all the time you could buy a "creader" and leave it attached to your ODB port and set it to automatically erase that code as soon as it pop up.
Otherwise you have to buy a new Evo and hope that it doesn't have this glitch.

 

But on a serious note, you COULD use that as an excuse to make the dealer buy it back.
You could do that now or just wait until the dealer have exhausted their money and energy trying to troubleshoot this issue.

 

Yes...it is a nuisance, and those w/out the creader get annoyed as well.

 

Everyone was a newbie at some point and I think its better that the member post here to get a informative answer than continue with misinformation and not knowing

You both have phones and PMs... use them...
