Thanks, I have changed the fuel filter and a bunch of black fuel came out and I have changed the idle air sensor, this helped smooth out the idle but still no real power. I also changer the plugs gapped to .060 and the boots from the coil pack, as well as one of the coils. ran it for a few minutes and check the plugs no fun in 15 degree weather. the #1 and #4 plugs clean and a little wet and the #2 and #3 black and dry. I also disconected the exhaust pipe at the manifold to check if it was a plugged cat. made no differance. What ohm reading should I get? as I am now leaning this way, as we recently put heat with fuel injector cleaner in it and the daughter did not put gas in right away.
