wilke3169 Posted September 12, 2007 Share Posted September 12, 2007 I have an LS 400, 1992 with tons of miles. A few months ago I replaced the water pump, timing belt etc. Has run and driven great since then. Drove the car last night with no sign of a problem. Get in this morning to drive and it is running like a 4 cylinder. No power, will hardly rev while in neutral. Seems like it is only running on half of the cylinders but it still runs smoothly. Is there someplace to start looking? Maybe a coil or something? It will sit and idle smoothly but sounds like a Honda car or something... Thanks in advance, Kevin Edit: I think its the ignition coil. I checked with a timing light and half of the plug wires are not showing power. So where is this coil located on the drivers side? Quote Link to comment Share on other sites More sharing options...
