What I have done so far:
-New spark plugs(Champion) and ignition leads (Bosch)
-Seafoamed (full can) the intake system through the hose.
-Ran some injector cleaner in the fuel.
-Cleaned throttle body with carb/choke cleaner.
-Unplugged MAF and it ran a little better so I assume its an air flow problem.
The outcome:
After I seafoamed and was letting it run I noticed a small air leak and I pinpointed it to the vacuum hose on the left intake to valve cover hose aka. (hose used for Seafoam injection) I noticed there was a cut in the middle of it and the hose was almost collapsed! So I took it off and taped it as a quick test fix and put it back on. Well, the truck started and found its idle and ran somewhat better but not 100%. I drove it around and it was no longer sluggish when taking off like it was and ran somewhat better but not as smooth.
So my question is would a ripped vac hose like this expain my poor idle? I did tape it up and it ran a little better but the hose is still faulty and feels very soft, so when engine is on it is sucked in almost collapsed. I went to the hardware store and got some $.59 cent plumbing hose for a test but it didn't want to fit as snug as I wanted it.
Ok i brought a coder reader today and here are the codes:
P1193
P0300
P0308
P0304
P1316
P1314
I cleared the codes it still is doing the same thing i drove it around my block and let it idle for 3min since i cleared them and no CEL lights came on. Still running sluggish. Any help would be awsome
