To give a little bit of background, the truck has 308K miles but it runs really well. It had a motor swap at 230k and it was switched with the same motor.
When I bought it there was a serious skip. I got it for a low price so I took a chance.
After reading several forums before going into repair completely blinded, I saw a lot of possible culprits that should be changed "just in case" so I changed:
Spark Plugs
Plug Wires
Coil Packs
EGR Regulator Sensor
IAC sensor
Cam Position Sensor
Did a coolant flush/bought a new radiator cap
Sprayed butterfly with choke cleaner
Ran seafoam through gas tank (very, very thoroughly)
Ran seafoam through brake booster vacuum
replaced all fuses
changed oil, oil filter, air filter
bought new tires.
Replaced radiator hoses.
NOW... after doing all this (whether it needed it or not) A lot of the rough idle and **** stopped. But now what is left is:
Oil pressure gauge jumps up and down when I first start it in the morning.
I hear a ticking around the front driver side of the motor
The shifter shakes and it idles rough until about 2.5RPM, but drives fine.
It gets a steady 21mpg (which I feel like could be better in a single cab)
Coolant overflows out of the reserve and leaks when parked.
(EVEN AFTER FLUSH) Coolant looks like YooHoo on the ground..
Check engine code reader says "misfire on multiple cylinders"
It get worse when you run the heat/air
Heres the deal though.. the hoses are new, they dont leak, it is a hard leak to trace. All the plugs, wires, and coilpack is new... So I don't get it.
I was told the injectors could def. be clogged and causing this..
***Things I know for sure***
1. Firing order is correct*
2. Cam position sensor was NOT scratched up on the inside*
3. Removing ANY of the 6 boots from the coil pack makes it run worse*
4. I did a very detailed vacuum leak test with brake cleaner.. no luck*
5. All wires are seated correctly
My main deal is I want the thing to stop the rough idle. I want to hang on to this truck as I have very little money invested and besides the (multiple) problems I listed up there^^^^ There is nothing really wrong, and as you guys know.. those problems only bug you, they don't really hurt anything. I just want to know if anyone sees a multiple-symptom culprit that jumps out as being a possible cause
*being that it is my only/personal/work vehicle, I have to work on it myself if at all possible.
Hope I didn't bore you, any suggestions help!!
