Starting problem DF140

When I try to start my 2003 DF140 (1900 hours) it starts right up but quits after 2-3 seconds. When I put it into fast idle it starts up and runs smooth . This problem is the same after a warmup. I sprayed throttle body cleaner with no improvement. Any suggestions will be welcome. Oh - my other 140 does not have the same problem.

Sounds like could be fuel problems. I recommend taking to a local Suzuki dealer to have the computer read. You can also check the fuel pressure.

Had mechanic over-turns out that it is/was a very sticky air valve. Took it off and sprayed it and manually moved it up and down. The computer program does not do anything more than energize the selenoid.-no movement recorded. With 1900 hours on it I will start to use throttle body spray every 3rd use to stay ahead of this corrosion.
