Random Misfire after H/C ?
Anyone know what could be the cause? I've taken the drivers side plugs out and inspected them they seem fine but i figured it was probably a broken plug from my headers rattling around in there when i was trying to realign them. Oh if it make a difference Stg 2 heads, TR224 114, ASP, Mac Headers, SY3500, Ported MAF + TB. Maybe i could just need tuning?
Thanks

Re: Random Misfire after H/C ?
normal.. any cam is gonna make misfires. I toggled my po3000 code off on edit. I tired setting the tables to 32000, but that only worked for like a week.
I get about 10-15misfires on each cylinder at idle.. its normal

I'm getting the same code in my 02 Z06 after a cam install. What tabs do u change the #'s in. Do u just change all the #'s that are 327## something? Thanks.

Re: Random Misfire after H/C ?
there is nothing u can do about misfires. Its just part of the cam life. You can raise the idle to help a little, but you still will have them. To turn the SES off you just toggle the p0300 code off on edit.

Go to "Engine Calibration" ->LOW RPM ->Edit whole table->VALUE=32000->fill value
->LOW RPM by CYL->Edit whole table->VALUE=32000->fill value.
->IDLE by CYL->Edit whole table->VALUE=32000->fillvalue.
You can review this in Edit User's Guide.
