Started missing (1 Viewer)

[Greasyfingers]

After a round-trip about 30 miles I stopped at a store for 15 minutes and came out to start it and it was running roughly. Had a miss . The engine is a 1985 2F in a 1980 fj40. Now it’s puzzling because it ran super for the 30 miles. Ran smoothly. What would be the first thing I should look at. After driving 5 miles home I pulled spark plug wires to see if the title would change . It got rougher with each one being polled but I wasn’t able to isolate which one was making it miss if that was even the problem. The only thing I did earlier was to accidentally down shift to first from 4th. That made the tires squeak. I was wondering if the timing gears could somehow slip but that doesn’t seem too feasible .
Well needless to say I would appreciate any advice before I start tearing into this 2F motor

Check your spark plugs, I had a similiar issue and there was a hair line crack on one of the spark plugs.

Maybe some junk in the fuel tank got picked up... fuel sock, filter, etc.?

when i accidently shift from 5th gear to 1st gear in my 83 FJ43L-KC , my clutch-less Direct Drive

Plastic AISIN Fan will sound like and feel like Old The Space Shuttle taking off @ Cape Canaveral when i

was young .......


that being said , i have rattled stuff loose like the Electrical connectors in engine bay and more often

a OEM TOYOTA Vacuum Hose off a Fitting .


im talking Newer Young Fresh 3mm OEM Toyota standard Hoses wit No tension on them freely floating

as they may sorta thing ...........


i would look for a part or component simply Rattled loose or a fastener such as a nut or bolt too


before i would start " Tearing " into your Nice 1985 2F .............


look for obvious and simple fix and issue , its there in plain sight , you just may have not seen it yet ...


good luck ,

Thanks that’s good advice. I decided on new plugs, roter and cap. First ,( needs anyway), then if still missing I’ll look for loose parts. It’s just strange that it was running so good until I turned it off for 15 min.

exactly , thats why it was a small but catastrophic minor event from down shifting vibration ..


maybe , based on my own personal experience ..........

But it was running good for 15 miles of my 30 mile round trip after the down shift. So what ever would have happened took time . 15 miles worth of time.
I fix everything and eventually I’ll figure it out but this is a engine I’ve never worked on.

I’m ignorant on that engine. Would it drop in my 80 fj40 ?

IMO , a 1985 FJ60 2F is a IDEAL Choice for a Minor only / Issue's Free , Minor only / Modification free

plug and Play Install into a 1980 FJ40


it's not really a Conversion IMO , more Modern best of both worlds Update



this is my opinion based on my personal views , im sure others have additional input here too .....




my 83 FJ43L-KC has a NON-USA 60 Series 2F , approx. month is May , year is a 1986 if the SOR.com

chart is Correct ?


my cylinder head does not have air injection Ports , or a 2nd Threaded UNION sensor Port either , to

side of carb ........



but , i do have a OIL Cooler Option , witch puzzles me a bit ?

im sure like anything else , it was made form many Doner Vehicals
