The code p0307 is a misfire code on cylinder number 7 which is the 3rd cylinder on the driver side need to check spark plug and plug wire for that cylinder as it can be anything from a sticking valve to a vacuum leak what i do to check this is remove number 5 cylinder plug and wire and install them on cylinder number 7 and put plug and wire from 7 on 5 and clear codes and drive till light comes on and see if it comes up with same code if it does you will need to check for a vacuum leak or a valve problem with cylinder 7 if it comes up with a p0305 then change the plug and wire

8 bolts...4 on each side witht he frame rails. 3 screws inside fuel filler door.
from underneath...back by the driver side tailiht area you should see a wiring juntion block with i believe 3 connectors...disconnect those. you may also have to loosen or remove the rear bumper for the lower part of the bed to clear. then all u gotta do is gently and evenly lift it off9 with assistants mind you(extra bodies)

the check engine light is on to tell u that one or more of about 200 possible problems has occured in the electronic engine controls or emissions controls and monitor system, this kind of leaves guessing out due to the number of poss problems so you must take the truck in and have the system tested for the troulbe code that is now stored in memory

These codes are for the evaporative emission system.The 455 is the vent solenoid.The 455 is a large leak in the evap.system.The vent solenoid I would replace because they go bad and will not work because they are under the vehicle in the rear of the truck.There is a bulletin for these and the vent valve is installed in another spot.The number for the bulletin is 02-06-04-037E.You should also look for a broken or loose hose or pipe that might have came off.Specially if you ran over something.If none found it could just be the vent solenoid stuck in the venting position.Good luck.
