check and see if the vacuum hose to the electronic "black box" is connected or cracked
It may be a lean run condition

I did some checking into part numbers and there was no difference in shift forks or drum from 86 to to 93.  So the fork changes were in all fj1200 engines.  Part numbers for shift cam and forks are "1TX" which is the 86 model standard prefix.   So only strange things (which could be part changes) in fiches were that the 86/87 have a few parts with "3CV" part numbers (89 prefix), which leads me to believe that back compatible upgrades or (hopeful upgrades) were done.

. I bought the 91 shift forks and did a side by side comparison with my stock 86 shift forks.....they are not the same part....the late model shift forks are much beefier in every respect....... once the part was updated the old part number disappeared.

BTW mine was jumping out of second quite regularly (i'm a big fan of the kookaloo) once that shift fork is bent the game is over..... but the dogs and windows in my 2/5 gear set were not in bad shape at all and could have easily been re used with just a bit of undercutting... which you are going to want to do even if you buy a new gear set as i did.... my advice is to save the money on the new gears and replace all the shift forks with the current part number shift forks instead.

problem solved.


Kookaloo!
