No it won't stay running if I use the throttle either. I replaced the fuel filter at the start of the trouble shoot. I have also checked the fuel system operation and done several other system checks. The TPS seems to be O.K. with 5.5 res. If I hold the contacts closed in the control relay it will run forever. I have tested the control relay and also tried another one the same results. Thank you for the input and would appreciate any help I can get.
