1500-2000 stumbling / hesitation / bog.
 

Hey, I searched and I couldn't find anything. Maybe I used the wrong keywords or something who knows. Anyway, for the last few months at random times my car has been bogging around 1500-2000k. It's an 89 Vert. I used to have the jumping rpms at that range but after I installed my safc-ii and got that set and adjusted my tps a few times and idle screw that all went away. But this random stumbling when taking off showed up.. I usually only happens, the best I remember, after I start my car and start to drive off. I have change the plugs and fuel filter. I havn't had my injectors cleaned yet.. and I do only get 15ish mpg. The car is all stock otherwise. Thanks.

check your tank for shit in it, mine would do the same so i put a whole new fuel system in it and it still had the problem, then my fuel pump went out so i changed it and noticed i had like a pound of corrision or some shit in there, i flushed it out and its been fine ever since....................

damn, While this is probably easy to do sounds like a pain in the ass. That'd be funny if someone put the shit in my tank.. Becuase they would be scratching their heads wondering why it didn't work.
