SES light
I have thrown a ses light.
I used hp tuners and i am thrown a P0300 code witch is a missfire I looked to see what cylinders are misfiring and they are #'s 7 and 8. I have changed out spark plugs, spark plugs wires cleaned maf and still throws thoes codes. Anyone have any other idea of what it might be??:banghead: |
do you have an aftermarket cam? Check the plug wire connector at the coil also (just had that on the gp)
|
how do you know its 7 and 8? P0300 is for random misfire...

I'm going to rip into the heads and look at valve spring, push rods and rockers tomorrow. (Side note I have not done any new mods) it just happin last week
|
PO300 means RANDOM MISFIRE DETECTED. That means mulitple cylinders. If it was a count on #7 and #8 going though the roof it would set a code for those cylinders.
If you had valvetrain problems you would know it by now, LOTS of mechanical noise, VERY poor running and power. Save your time. You may have just got a tank of ****** gas. |
:woot:
Found out it was a nice header leak Got that fixed no more ses light |
