Broken 4runner Need Help

[hebercity]

Ive got a '94 4runner that isnt running so well and im stumped. It starts to overheat after about 2 blocks of driving, i thought it was my thermostat but i just replaced it and no change. Also it has been idleing very odd.. it feels like one second the engine isnt gettin enough fuel and the next its feels like its getting too much. So any input would be greatly appreciated.

yeah i checked the coolant after the first time it overheated and it was low but it still had coolant in there... but im not sure if its gettin coolant.. and yeah its been acting pretty sluggish

The overheating problem sounds like you have an airpocket in the system. The 3.0 has a high spot in the back of the engine. Its a rubber hose that runs across the back dis connect that and see if there is a pocket there. I wish i could make it more clear by showing you a pic but thats where an airpocket would be. If its continues to overheat your radiator may have a blockage in it from just being old.

toyota 3.0 truck motors are by far the most disgusting motor ever, do yourself a favor and get rid of that pos, get yourself a 22re, its lighter, makes just about as much power as the 3.0 and its bombproof, and it dosent suck to work on
