ok had the injectors sent out as well as injection pump to double check proper operation. injectors were all stuck open!! injection pump was tested and told good to go. put everything back in the truck and starts easy peasy. EXCEPT, now i am having a problem with a slight surge down at lower rpms. i adjusted the idle up and all went away but it does seem like a higher rpm idle ~ 950-1000rpms. when NOT applying any throttle at all and trying to use the steering the engine dies. using lift is ok. when using tilt, side shift and this carriage has individual fork positioners, the engine dies sometimes. i found an old service gram FS06-001 that specifies a different injection pump and different injectors to be replaced. also it specifies that when timing you time to.039-.041" so i retimed to said specs with original rebuilt injection pump and rebuilt injectors, no changes in operation. we are at elevation so i did try to advance a little bit but still with no changes and always wanting to kill the engine when trying to steer. boss is breathing down my neck on this unit so please help me out quickly on this guys! Many thanks in advance!!
