I've been working on an '89 SC that started out running fine, just had a bad water pump. I figured I'd change motor mounts, plugs, wires, and the crank sensor while it was apart. Got it all done, and fired it up and took it around the block. The engine seemed to be missing pretty bad, so I double checked all my connections and firing order (123, 564). Took it back out and no change, except that the check engine light came on at about 5psi in 2nd. I checked codes and came up with 21, and 54. So I looked at the crank sensor and thought maybe it was a little too close, so I readjusted and tried again. SAME THING. So I put my old crank sensor back on thinking I may have fried the new one somehow (old one should be good, I just changed them cause I was down there). Now it's still rough, but I'm getting the following codes 21, 54, 24, 77, and 74. I checked spark at the "coil" and am getting strong spark on all cylinders. I'm stumped. I'm trying to get the car running good so I can sell it, after buying my '95 SC.
If anyone has any ideas or suggestions.. they'd be realy appreciated.
Thanks
