Customer Question
I have a 2005...

I have a 2005 dodge ram 1500 with a 4.7L V8 with a misfire.

Mechanic's Assistant: How many miles are on the car? Is it a steady misfire? Or random?

127k miles, intermittent at times, sometimes worse when i shut off engine and start back up, i have replaced the o2 sensors, crankshaft speed sensor, all 8 spark plugs, had iridium plugs in before replaced them with traditional ones. Replaced coil on cylinder 8 since i had p0308 code. Then when i still got that code again. I swapped out cylinder 6 with cylinder 8 coils and still have p0308 code. so its not the new coil. not sure if its wiring going to coil or injector.

Mechanic's Assistant: Are you fixing your Ram 1500 yourself? What have you tried so far?

Yes, and please see above comments

When i replaced the o2 sensors and the crankshaft speed sensor it improved for about a day then starting receiving code again and misfiring, so i am basically back where i started again.

I will also add that we had two different compression checks performed and both check out OK.

I AM VERY GLAD THAT I TOOK A CHANCE ON YOUR PROBLEM SOLVING SKILLS. I WAS SUCCESSFUL IN REPLACING THE FUEL PUMP. MY TRUCK RUNS LIKE A CLOCK. IT RUNS LIKE THE DAY I BOUGHT IT.

I GIVE YOU ALL THE CREDIT FOR YOUR DIAGNOSING THE PROBLEM, JUST FROM THE SYMPTONS I GAVE YOU OVER THE e MAIL. I WILL USE YOUR WEB SITE AGAIN AND REFER MY FRIENDS. THANKS SO MUCH FOR THE HELP.
