Multiple Cylinder Misfire! What Do You Think?
#1
![Default](/forum/images/icons/icon1.gif)
My 03 STR picked up 5 codes last week. PO302, PO306, PO308, P1314 and P1000. The first 3 are Cylinder misfires for cylinders 2, 6 and 8, P1314 is Malfunction of Control Ignition System and the last is Fuel Air Metering Aux. Emission Controls. The problem is happens whenever I accelarate hard. Whenever the RPM's reach near redline, all the lights on the dash come on and the restricted performance light comes on and it won't accelarate at all until speeds drop below 65 or so or maybe when rpm's come down far enough. Then the restricted performance light goes out, but the engine light stays on. Happens every time. Do you think it could be coils, bad plugs, or what? Any help would be greatly appreciated!

Also, does anyone think that this could be caused by oil on the spark plugs from leaking valve cover gaskets. Are cam cover gaskets and valve cover gaskets the same thing. Does anyone know of a link that gives procedures for replacment of this/these gaskets. Also, what are the tensioners I keep reading about people replacing. I know, I have alot of questions, but this problem really sucks and I need it fixed ASAP. Thanks.
