Engine dies randomly

[truggy83]

My 2.5r engine was running great until I touched the idle speed screw. I tried to slow the idle speed down so the wheels wouldn't spin when the truck was upside down. Ever since than, the truck will just randomly die. I tried resetting the needles back to where they come from the factory. I replaced the glow plug. The truck will sit there and idle in one spot for a minute on it's own and accelerate fine. The truck will be driving ok and it will just die on its own. It doesn't seem to bog down and die. It just quits. Any ideas what may be wrong?

You might be too lean, or you closed the idle gap too much. Did you turn on the rx and your transmitter and apply the brakes before you set the idle? If the idle gap is set too small and you apply the brakes while driving, the truck will not get enough fuel because the gap is too small. The idle gap should be around 1mm (thickness of a credit card).

yea I applied the brakes. I think I figured it out, the lsn was too lean. I richened it out and it seemed to work good.

Glad to here you figured it out.
