Ok I want to let everyone know that my Tahoe is fixed and unlike most I’m gonna tell you how it was fixed. My fuel pump was only 6months old pressure was 55 not running 61 running which most people would believe to be good fuel pressure. Apparently not. New ac Delco fuel pump and my problems have been solved. I think gm says 60 to 65 for the fuel pump to function properly. So this spider injection must be very sensitive to any lower pressures. New pump and it runs fine now. Hope this helps anybody else having this issue. Thanks and good day
