Hello new poster here. I have been wondering around DF for a long time but never posted before. But I have a problem with my truck and this is the best place to find answers. First off I have a 03 1500 5.7L 4x4. and I never had any problems since I bought the truck in 07. And I have no performance mods. But this morning when i was leaving work the truck was running fine for about 15 mins then started stuttering and lost all power. The engine started clicking and the ETC light started blinking. I pulled off the road and it took everything I had to stop the truck, I was only driving about 35 mph. After i stopped the CEL came on. The truck still runs but idles very rough and it still has no power brakes. I pulled the codes and all I got was P0300 and it does feel like its misfiring pretty bad. Anybody have any ideas on what could be wrong?
I appreciate any help. Thanks guys
It was a problem with the 03 Hemi's. Pull the valve covers and check them all. Personally, if you find a bad one, I would replace them all so you don't lose another one later down the road.
Good call Hammer. Pulled the valve cover and found a broken spring on the number 1 cylinder. Time for some new springs and possibly a valve job hopefully just springs though. Never replaced valve springs before. Wish me luck
Well parts are ordered. I ordered the 6.1 springs and rods. And the spring tool from Weedahoe. Thanks guys for all the help. I'm sure i will be asking for more help when the parts get here. I have a picture of the broken spring but cant figure out how to post it.
