Hi Ladies and Gents,
Youll recall my earlier post here http://jeepkj.com/forums/viewtopic.php?p=36350&highlight=#36350
I replaced all the plugs with Champion Copper Plugs, Installed a new air cleaner, and a new battery, cleaned the throttle body with 3M Throttle body cleaner.
THis was last week. The jeep ran great the whole time until today. She calls and says the Check engine light came on as she picked up her daughter. When she came out and started it, the light was blinking. Any time she tried to go over 35, the truck would surge and buck.
She was less than half a mile from home, so I asked her to limp it there. I got my code scanner, and I got Codes:
P0300
P0305
P0306
P0355
I immediately pulled the #5 and #6 Coils and checked the plugs, to make sure the plugs were snug. The plugs were fine. I drove the truck and it was fine, next stop light, I accelerated, and it bucked when it got to 40 mph, so I pulled over, pulled the codes again and got the same set. I then selected the "Clear Codes" button, and drove the truck, which drove fine again, but the light was on, not blinking, but steady.
So here I am. Light is on, but truck drives fine, same codes present.
Anyone?
Thanks in advance guys and gals!!
