Hello and thank you for all the knowledge that’s shared here!
We have an engine idle problem that has my son and I stumped:
Our ’82 FJ40, all stock original, with emissions, etc., had some oil leaks so we decided to embark on a father-son project and completely rebuild the 2F engine and re-seal the transmission and transfer case.
Our FJ has 123,000 miles on it.
When we started out, there were no issues other than the leaks.
After the rebuild, which included rebuilding the Aisin carburetor, it ran just fine.
After our third short outing of less than 12 miles, the engine would no longer idle. It did fine at higher speeds and would start right up if the throttle was partially open.
After reviewing the thorough information found here, we replaced the fuel cutoff on the carburetor (also making sure it actually ‘clicked’ when energized. No change.
So far, we’ve:
Any ideas or suggestions would be greatly appreciated as we’re out ideas.
Many thanks!

So far, we’ve:
- Verified ignition timing (several times).
- Spark plugs look fine, maybe slightly damp.
- Checked compression (still good and even across cylinders).
- Went through the carburetor two more times.
- Replaced the fuel.
- Replaced the fuel pump.
- Verified all vacuum tubes are correct
- Pulled the manifolds and replaced the gaskets.
- Used propane coming from a tube and introduced different areas to see if the engine speed changed (to check for vacuum leaks), with no difference noted.
Any ideas or suggestions would be greatly appreciated as we’re out ideas.
