so heres the story. about three months ago my truck was running fine. i had a holley tbi. decided i might get better performance/fuel ecomony if i put the stock TBI on with upgrades( adj.fuel pressure regulator,injector spacer,TBI spacer). installed all the parts and the truck ran terrible. passenger side injector would not fire. replaced bad injector with new one from autozone. it now ran ok, but had a poor idle on cold startup and seems to miss/starve of fuel above 3000rpm&heavy throttle. i could also not get my fuel pressure to stay consistant. it would be 14 when i start it up, then go down to 11 after driving. so i decided to put the holley back on and hopefully fix all these problems. the full throttle miss went away, kept a steady 12psi,but still had crappy cold startup. drove it like this for a couple weeks, then i started to get a miss under cruise. almost like a hiccup. two days later it was so bad i couldnt even drive it.decided i had enough of this and towed it to my mechanic. we pulled the air cleaner and the pass side injector was not firing.for some reason my truck keeps killing that injector. he said since its happened on the other tbi,and there is no check engine light, its probly a faulty ecm. he replaced the ecm/prom with a "rebuilt" one, along with a dist. module. drove home and the truck ran fine. next morning still had the crappy idle @ cold startup, but ran fine otherwise. next day i started to get that hiccup. now today the hiccup is getting worse, and the idle isnt steady anymore again. im willing to bet the pass. side injector is starting to crap out again. any ideas? this damn thing is driving me nuts.
