WTF!!!!!! this one has got my feather all ruffled, my 89 mk3 developed a sputter @ about half throttle it started with a slight poping and sputtering @ idle then it got worse it started to do the same thing through out the power band from about 2,500 to 3,000 rpm and on out.
I first changed the spark plug wires and plugs gaped them to 31 and in they went, still same sputter, changed the fuel filter (factory), still same thing sputter. Change the coils, nothing still sputter. changed fpr (factory) same thing SPUTTER!, instaled a sun hyper voltage/grounding kit, still same thing, pulled out a set of lucas 550 injectors i had purchased from eko ramedan. took them down to rc(great people) to have them serviced purchased the nessesary clips instaled them along with a lex afm i had and FUCK!!!!!!!!!, STILL SPUTTERS FROM ABOUT 2500RPM...........I do have a holly fuel pump that is probably a year old, top cat is gone middle is still there, hk$ so called filter, & apex-i exhaust.
I don't think that my fuel pump would go bad that quick. could it? Everything was fine until i ran some hi test gas and some stp octane booster, that when this whole problem started. After i instaled the 550's and the lex afm the car run excellent @ idle and @ cruise speed but half throttle sputter sputter again. grimjack, 1jz, and the rest of all you boyz out there what in the name o' toyota is going on with my ride. do you think maybe the fuel pump could have been damaged by running the fuel cocktail ruined it? I just don't get it. the only thing i noticed after the fuel & afm upgrade is hi idle, other then that it runs excellent till i rev 2500 in second and forget it puff putt sputter. Its not a back fire its a sputter.:cry: :1zhelp: :bigun2:
