89 Toyota pickup idling problem

[Tkowens8]

Ok I have a rebuilt 22re everything is brand new in it and on it from the bottom up, obx header no cat thrush muffler, when it's cold it'll fire right up and run fine, but as it gets warmer like if I was to drive 10 miles when I get to a stop light it idles real low and sounds like it's got a miss or out of time but that's only when it's been running, I can shut it off for 5-10 mins and start it back up and it's fine again buy today I went to town and it started doing it even after I stopped for a min but by thE time I got back home it wasn't doing it again, any help is greatly appreciated, also I can hear some gurgling comming back into the breather box

you probly have a coil braking down or a wire bracking down

it could also be an air pocket in the coolant system

2X Checking you plug wires, boots, and coil. Just had the samething happening to me and it was one of the wires.

When the motor was rebuilt they were all replaced but I'll exchange them since they were under warranty, I just checked and k ow the truck is throwing a 25 code Which is lean air fuel mixture any ideas there?
