View Full Version : losing power

i was wondering if anybody could give explain what is happening to my 94 sc 5sp and what i can do to fix it. i recently got it out of the shop after replacing the balancer with a bhj unit, new plugs and wires (motorcraft), cam sensor, crank sensor, icm, new computer, iac, tps, re-sealed ic tubes with ford kit, still had a good coil pack. it ran fine for about 3 weeks and begin to die at idle. i was told by one of you guys to check the ic tubes for leaks. I found it leaking at the inlet plenum where the ic tube attaches. i re-sealed it with copper rtv compound. it now idles with out dying, but fluctuates rpm and as the engine heats up it begins to lose horsepower considerably. what could be causing this? Any help would be appreciated.

Do you still have the stock O2 sensors in it?? If so, might want to change them.
