Hey there, new member here. I've posted on ttora and PBB and Yotatech about these problems. Nobody has any ideas and i'm at a loss, so maybe you guys can chime in too.
My truck is a 1998 Tacoma w/ 2.7L 3RZ-FE, and a 5-speed.
Here's a re-cap of the things that have happened to this point with this truck.
The headgasket blew/was leaking. The truck DID NOT OVERHEAT.
I replaced the headgasket, then had to replace the fuel pump, the injector at 3, and some other stuff.
Then, i found i had shit compression on 3, pulled the head again and found some pretty crusty valves.
So, after replacing the valves, i put all the valve lash to spec for ALL the valves (between .012 and .016 exhaust, .006 and .010 intake)
So, here we are, a new fuel pump, new headgasket, new injector at 3, new ECT, and a bunch of work.
I still have a P0303, and a P0300.
I've swapped the 2-3 coil with the 1-4 coil and no change. I checked the plugs, and they even LOOK normal (sort of tan on the tip).
I haven't got a clue what to do next.
My LTFT on the last check was only 1.5%, which is in range of what it should be, and actually shows an excess in fuel, but not what i would say is worthy of an actual misfire.
I have NO vacuum leaks, and i have NO other codes. No codes for O2's, or Catalytics..
Anybody have any ideas?
