Hi first post and first FJ80 We needed an all wheel drive, 4 door, SUV to haul the new baby around with, so I found a high mileage 1994 a couple of months ago.
I've been fixing oil leaks and after replacing the distributer o-ring I decided to check the timing and adjust if needed. I have also read on here that these benefit from running a little more advance than factory specs.
I found the directions on www.lcool.org.
When I check it idling normaly in park at operating temp I'm around 16-17 degrees. It should change (lower to factory spec of 3) when the service connection is jumpered to "service mode" but it doesn't. However the check engine light does flash so I know the jumper is connected correctly.
Do you guys have any ideas?
It also seams to have a rough idle at times after it warms up... probably not related but figured I would mention it.
Thanks!
ROB
