Droped in my new custom and the next day an error code came up. Checked it out today and it was

P0300 - Random/Multiple cylinder misfire.

YIKES! This cant be good. Any suggestions? Anyone have a familiar occurance?

 

Do you have a cam? If not, check your plugs, or wires. Makes sure they are connected good on both ends.

 

i had a misfire in cylinder 7 the other day. i changed the plugs and wires. now no SES.

 

Well, i "touched" all the plug ends, they all seemed tight. The Engine light went out today, something could have been lose? Dont know, Ill keep an eye on it.

At least its gone for now!

 

that's good. and as long as the engine runs normal, you can be at ease

 

Damn light came back on. The shop said the batch of PCM he got are "sensitive" to this code. Sending it back to get fixed. Interesting, hopes it works next time.

Any other thoughts or experience?

Thanks
