where is the vent ?

[79coyotefrg]

go get a new tps for the 90 and install  any of the parts you used that could have been water damaged should be replaced

 You need to do a fuel pressure check. It could be the pressure regulator or the fuel pump,clogged fuel filter.

[Sundowner]

anytime you remove a TPS from a toyota it needs to be RECALIBRATED, as per the factory service manual.

the truck will buck at crusie, and surge and die at idle.

this is a simple procedure. it takes all of five minutes with a mutlimeter and a feeler gage set

   I think shortbus is right I had the same problem w/my 89 toy the fuel filter has sucked up rust out of tank.    (the truck had sat up about 8 mos. when I got)

the vent thing is just to ez to be the trueble, butt just in case try it with the gas cap off. that will rule it out.

[Mike D]

just pour gas on the truck and lite it on fire and it will solve all your probs.

with teck advice like that, I'd be out of a job!    (don't do it!)

Hey gizmo,

This happened to our local friend Louie from the Wicked Wheelers on his truggy with a 22RE. His would run fine for about 30mins and then die for no reason. Then it wouldn't start back up, but if you waited about 10mins then it would fire up and run fine.

I told him to all of the diagnostics I could think of including checking for grounds and everything, and then out of desperation I told him to check his ignitor and/or coil, and it turned out that it was his coil. He replaced it and so far its been running perfect.
Something wrong with his coil was causing it to die after x-amount of time. Weird..

[FATB0Y]

  If you end up having to replace the coil don't buy aftermarket (autozone...etc) you'll B sorry.
Just a heads up a friend of mine got one from A Z and he still had a bad miss . Bought one from local toy dealer and the miss went away.

how deep was the mud? if it was deep enouph it could of screwed up just about any thing thats electronic,  computor, coil/ignightor(i might have one if you need one), sensors..........................................................................................
