my ses light is on and throwing a P0300(random misfire) can anyone recommend what to do or give a better diagnostic of this code?..the car is an 05 procharged coupe the procharger has been on the car for 18mo.(new nkg plugs were installed) and the ses light came on 2 wks ago. i took it on a 200mi trip w/o the belt on the prcharger..on the way home from the trip is when the light came on.
any help is greatly appreciated

 

anyone?

 

Alot of us FI guys get this code and just clear it out.How is the car running.

 

car is running normal..should i just disconnect battery for 2 days or so to reset?

 

Just go to any autozone or pepboys and they can shut it off for free.Unhooking the battery will not shut off the cel like it did with pre 1996 cars.

 

ill give that a try..thanks for the help superchargedg

 

Did you install the plugs? I had this code for a while, then replaced, gaped, and torqued new plugs. Haven't seen it since. Make sure the plugs are in/torqued all the way, then clear the code and see if it comes back. GL

 

the code went off today..i didnt do anything to it..its done this 2 times now..its came on then went off..i will take your advice if this continues to happen..thanks ice
