Falling Idle!

[Porkchop]

My 93 fj80 started to idle erretically and die when ever I come to a stop or slow down when going down hill! It also died as I went around a corner at idle. If I do get it stopped with out dieing the idle returns to about 650 rpm and holds fine ? Any suggetions would be great!

how long has it been since you changed the fuel filter, PCV Valve, plugs, wires, rotor, dist cap?

I will go through all of the tune up items and check back if no success. I probably over-reacted but I am not used to nay problems with this truck! Thanks for the feedback I'll try those!

Check for vac leaks, too. Especially in the large tube from the air cleaner to the throttle body.

There are also lots of small vac hoses that can come loose.

Air leak in the intake hose or vacuum leaks.

sounds like vaccum line somewhere, did you change anything underhood recently?
