After running great for a good long while , and getting me to work and back , suddenly today my Caprice lost power and began running very poorly. I first thought the fuel pump was failing , but disconnected the wire that goes to the distributor , that you unplug to check and set the timing and the engine ran good once again , but with the service engine light on. I replaced the knock sensor and now it is running good once again. Very Happy

Cool thanks. My 92 is running like crap and I can't figure out why. Will try this and see what's up...
