okay, the problem I'm having is a rough and very low idle in my rig. At first statup, the idle stays at about 1000, but after the engine heats up, the idle starts to fluctuate between around 600-800, and sometimes drops as low as 400..... Could this problem be caused by clogged injectors? I've got a 1990 350 with TBI. The Fuel filter was just changed, so I don't think this is the problem. Any help would be great! Where did all these damned dirty apes come from!?!
