    FJ40 2F Engine Idle Issue, not the usual fix, ideas?

    2nd replacement FCS fixed it

    Where to start with 2F engine stalling

    I had posted earlier about our idle issues, which now appear to be solved. The original FCS would click, but we replaced it anyway. The replacement would also click, but we still had idle issues. This included when the FCS was powered directly from the battery. We replaced with another FCS from...

    FJ40 2F Engine Idle Issue, not the usual fix, ideas?

    Update: The idle problem with our FJ40 Landcruiser seems to be fixed! First, thank you for all the suggestions!!! ToyotaMatt and Spike Strip mentioned the FCS could still be an issue, even if replaced. I ordered another one from SOR, we installed it this afternoon and now have a fairly smooth...

    FJ40 2F Engine Idle Issue, not the usual fix, ideas?

    Right off the intake manifold, just below the carburetor. Valves were adjusted at the time of the rebuild, then rechecked after a warmup. To recap, the engine idled perfectly after the rebuild, drove it on several short trips. On the way back home from the last trip of maybe 20 minutes, it would...

    FJ40 2F Engine Idle Issue, not the usual fix, ideas?

    Sorry if I offended, I started calling them FJ's sometime after my first 1969 Landcruiser FJ40 with 3 on the tree. The timing is dead on the marks, set per the manual, but I have not tried advancing the timing to see if the vacuum changes. Altitude is ~4,200'

    FJ40 2F Engine Idle Issue, not the usual fix, ideas?

    An update: We finally had some time to devote to the FJ and our idle issue. The good news: The replacement Emissions Computer arrived from Engineer8000, it looks really good and did solve the low voltage going to the FCS. A really great job with communication and the quality of the unit, plus...

    How would I go about purchasing this unit from you? I trust a unit you stand by more than a unit pulled from a vehicle...

    Yes, we removed the EGR completely, and checked it with a vacuum pump. It seems to be working normally.

    FJ40 2F Engine Idle Issue, not the usual fix, ideas?

    It's been a while since we've had time to work on the FJ, but want to get back to it. I'd like to order an emissions computer and another FCS. Who do you recommend we purchase from? I'd like to support vendors here, if possible.

    thank you, we'll check them out!

    FJ40 2F Engine Idle Issue, not the usual fix, ideas?

    Thank you Matt, I appreciate the encouragement! Going back to how the problem started, we were on a short drive and the idle issue surfaced as we neared home. Keeps me wondering what could have changed in a short amount of time. I think we'll proceed with another FCS and also an emissions...

    FJ40 2F Engine Idle Issue, not the usual fix, ideas?

    It's a USA spec, with the factory high altitude setup. All the emissions components (and there are a lot of them) are in place and connected. We'll be taking a vacuum reading next, currently waiting on a tachometer to arrive (as we want to determine vacuum at the lowest possible rpm that it's...

    The replacement fuel cutoff could be a lower quality replacement. The old one does still work though, the O-ring is intact, but does show some minor signs of cracking. We only replaced it to eliminate it as the cause of the idle issue.

    FJ40 2F Engine Idle Issue, not the usual fix, ideas?

    Thank you, do you think this could still be the case, since this is a 1982 FJ?

    Thank you, checking into the EGR next (that would make sense if exhaust is getting pushed into the intake).

    FJ40 2F Engine Idle Issue, not the usual fix, ideas?

    An update... We finally had some time to implement some of the great suggestions, and decided to start with the fuel cutoff solenoid. We removed and checked it for operation, no problems observed when connected directly to the battery. The seal at the end of the tip looked good. To verify it was...

    FJ40 2F Engine Idle Issue, not the usual fix, ideas?

    Thanks Matt, I have a vacuum gauge, but was not sure what vacuum is typical at higher rpm (since it won't idle). What would you expect to see at a higher rpm? And where would you connect to take the reading?

    Thank you for the reply, there are two wires, one is hidden by the angle. The unit energizes when the ignition is turned on, and stays energized as confirmed by a voltmeter at the leads.
