P0300: Random/Multiple Cylinder Misfire Detected
P0301: Cylinder #1 — Misfire Detected

Is there not a list of CEL codes on this forum?

 

 

check your plugs, check your ignition map (rule of thumb 1degree of retard for every psi of boost...just a reference), im not familiar with greddy management so check your software and make sure your running whatever software that is best suited for the tc (if there is different software)

 

also what are your afrs......that will deff help

 

nope you need to post one huh

 

its dark outside and cold plus tomorow will be a snow storm, maybe new year thursday I wil take a look

 

Yes Chris, yes I do.

 

how is it running? is it missing at idle or under load?? Check plugs, check spark, then check the flow of the injector.

 

idk how much you know but if you need a hand let me know im not far from lowell and i have the rest of this week off from school (but i do work).

 

Check the injector, coil pack or the spark plugs. Try switching them around and see if the misfire move to another cylinder that will help you find out the cause of the missfire. I can stop by and help you if you want bro.

Also Davedave hit me up.

 

I went to Cess house I switch the coil and reset cel now waiting to see if cel comes back then check it for codes

 

hope it works out.....good luck

 

no signs yet finger is cross

 

Ok yesterday I got the Cel again and same code

 

it might be your tune just like me. atleast you got 2 i got 6 lol.

 

Check your plugs. If they're fouled, then that's what is causing the CEL. But you can't stop there, because your tune is the thing that will cause the plugs to foul out.

 

99% sure its caused by tune. Post your AFR's

Does it stumble when it throws the code? Are you under boost, cruise, or idle?

 

I change the plugs now it idle better, and so far no cel yet, I will give it another week of driving. afr for idle is 15-16-17 afr for cruising is 14-15 afr for boost is 11.2-12.3 at 8-10 psi
