HELP!! :confused:

On the way back home (San Juan islands WA) form Zimfest 2006 in Eugene Oregon, my FJ80 started acting up. It would just start stuttering and staling an losing power. I have read that it can be the EFI main relay? If I pulled in some where and let it set for 30 minuets I could get another 50 miles out of it. It never completely died but would lose power to the point of me driving the shoulder at about 30 miles an hour while it chugged along. Any ideas / help, would be appreciated.

I also have another ongoing problem with oil being blown in to the air intake from the valve cover. Every few months I have to pull the pull the air intake up to the throttle valve body and clean it all out. I replace the now clogged up PCV valve and clean all the small hoses from the valve cover to the intake manifold. After all this and a new or cleaned set of plugs it will run just like the gutless wonder it always has been. Any one have any ideas why it does this?
 
Since you said FJ80, I will assume it's a 3FE. What your describing sounds similar to how my 2F acted when the fuel filter needed replacing. A clogged PCV valve could do the same

mine did the same thing the filter in the fuel tank was the problem

Ah, yes. I hope he'll post back and give us more info, but that is a good call; besides the standard fuel filter, you need to suspect the "fuel sock" pre-filter in the tank.

This sounds precisely like the symptoms I had on the 92 FJ80. It was the fuel filter prestrainer "sock". Click Here for details.

I suggest you purchase the FSM (Factory Service Manual)if you haven't already done so. It should arrive in about 5 days after the order is made. It's quite helpful because the diagrams are much better than the Haynes or Chilton type manuals.

Oil in Intake.
