Throwing both of these and I'm not sure why. The misfire has been an issue for awhile now (it comes and goes) but the c1130 is new. I've seen a few posts about the c1130 being fixed with new crank or cam sensors but don't want to just randomly start replacing sensors and hope for the best. Car is an 03, 6spd, with a osiris reflash. Any help is appreciated.

 

it is throwing codes because something isnt right..... but my internet mechanic crystal ball is not working today

 

So very helpful.

If I had more info to give you I would but that's pretty much it. Also noticing a slightly jerky acceleration at lower rpms but that's about it. Drives fine otherwise.

 

Your P0300 = random misfire and could be something simple like a knackered spark plug or coil.
C1130 = engine signal 1 which could be a faulty ECM, ECM fuses or faulty ABS control unit
hope this helps to point you in the right direction.

 

^^ agree with Sam on ignition parts.

The misfire could be 1 of dozens of items. From the "free to check" dept, make sure the intake tubes are connected correctly and snug. On the stock airbox there is 1 underneath also, ck that hose for cracks. Listen for vaccuum leaks, too. Gl.

 

Just read your post again and just had a thought (1st one this month), when you had your
Osiris reflash done could this have possibly b*****ed something up?
