MisFire Codes

[Jesse 135i]

I just got my 1 a month ago. About 1100 miles on it now. Installed a JB3 and Injen intake already.

The SES light came on one morning a week after the install of the JB3. P0304 and P0306. Talked to Mike at 54 tuning and he said nothing to really worry about so I cleared the code and fine. Car perfect again

A week later the SES light comes on again in the morning at start up. Now I am worried! P0300 and other misfire codes.

Has anybody had these codes?
What can/could it be?

Clear the codes again and three days late zero codes but I am waiting.


Thanks

I had a misfire code on mine, they replaced one of the injectors. It ran fine with no codes ever since. I don't remember the exact code numbers though.

If it were me, I'd pull the JB3 off for a while and see if the codes come back. If they do, I'd take it to the dealer (after a BT scan to make sure there are no tampering codes) and let them diagnose it. There have been several people here who've had codes like that, and it seems to be the coils.
just my .02

That is what I was looking for. Thanks man! I was think it was the car not the JB3. You said it may be the coils cool. I was thinking something like that. Thanks again

Let us know how it turns out.

My car threw some misfire codes and would go into limp early on, but oddly enough it hasn't done it since I put the JB3 on.
