Ok, i pulled out my 2.5 tmaxx today to do some runnin around. I put my glow plug warmer in and pull the pull cord and it fires up after the 2nd pull, but, everytime i take off the glow plug warmer the engine dies. is this a sign of a bad glow plug? also, when it does start it idles really high even though i have the idle set screw set to 1mm or even less. i just cant get a good tune to this engine at all. when it did run with out the glow plug woes, it would die everytime i gave it throttle. any help?
If the idle is high and the idle screw is set to a small opening( I assumed you checked it by taking the air filter off), then it's too lean. Sounds way to lean. As we always say go back to factory settings on all the jets LSN and HSN and try again. If it starts and runs at a reasonable idle but still dies when you pull of the glow igniter then change the glow plug.
Sometimes after awhile of adjusting the needles for different days etc. we end up forgetting what the needles are set to. If you are still having problems try changing the fuel lines, a leak can cause a lean mixture as well.
