Have a customer that had a code E-38 on their Nissan forklift(MCP1F1A15LV) this was about the 5th truck in two weeks that has had this code,rebuilt the NIKKI regulator/converter and set my fuel PSI to 4 1/2 pounds, the trucks starts now but wont only idle very low and wont rev up. I took the injector out and took off the injector holder and cleaned any tar that i could find that may of gotten past the regulator,was wondering if anyone else has had this happen to them on a code E-38 on a Nissan K21 Engine? the truck still dosent want to rev up when you step on the pedal it will start and idle half way decent but no throttle and there are no codes showing on the dash now?
I have a new injector am going to install this morning and see if that cures my problem. I am thinking a bunch of tar got past the regulator when it blew a diaphram and now the injetor and injector holder have a bunch of tar in it clogging things up and not letting enough fuel thru???
