so, after working on the problem and reworking on the problem, I'm not so sure that it is actually missing, the truck thinks its missing, and after it confirms it shuts off the cylinder, making it miss for real, (not sure that makes sense). the wire has continuity for the injector from the computer. maybe bad cps? I didn't replace that at first when I replaced the engine, only later. I'm about at the end of my abilities. think I may need to take it in to a professional. thanks for all the replies everyone.

Sorry we wern't the help I thought we could be. Maybe you are the first to experience the same issues. If you do find a repair it would be helpful to another if you post your resolve. Good Luck!

OK exactly what is broken. Hopefully it is covered by warranty. Nitro is not prone to mechanical engine breakdowns but electrical ones, yes. Thanks for the follow up. Good Luck with the repair.

Looks like cylinder one has one of the rocker arms on backwards.

I had a PO302 error code (#2 cylinder misfire detected) on my 07 Nitro R/T 4.0 engine. It looks like at least for now I corrected my PO302 error code with a simple additive. Chevron Techron Concentrate Plus Fuel System Cleaner - 20 oz. Maybe in my case it was one dirty spark plug or injector? I'm sure if I drove the Nitro more it would not have been an issue.

My R/T is a very low mileage vehicle but lets face it, it is 12 years old and could use replacement of many of what triggers the Nitro to throw this Code including:

Replace Spark Plugs
Replace Spark Plug Wires
Replace Coil Packs
Replace Fuel Injector(s)
Repair Vacuum Leak
Cam or Cam Sensors?
Low Compression?


Don't know how long this low cost simple repair will keep working but it will go to the Dealer since I do have a backup "Lifetime Power train Warranty" if maintenance replacement items don't solve any future error codes. No way am I going to try to figure out myself and repair my Nitro when I might end up like some others with no resolve, just in case it could be a covered engine issue.

Give this a try first as I did and maybe you could solve this issue as I did.

Since the instructions state to add first then fill your gas tank and I already had a full tank I added it anyway and let it set overnight. The next day I started it up and didn't even drive it but let it idle in the driveway for a few hours. I could tell it was not rough idling as before! When I took it for short drives later it appeared to be OK and a few days later I erased the Service Engine Light on the dash with my OBD2 card reader, and it has not come back on!

GOOD LUCK!
