Please help. I've got a '97 LS400, 192,000, runs great and no smoke. It started randomly cutting out and then dies. At first it was hardly noticeable and it would not die, now it's more frequent and almost always dies. Nothing obvious under the hood, cleaned the throttle body and replaced the spark plugs and the problem still exists. The following misfire codes come up repeatedly, P0300, P0301, P0302, P0303, P0304, P0305, P0306, P0307 and P0308. It happens at all speeds and seams to happen more often in warm weather.

Hi again, thanks for all the response! I took everyones advice and purchased a reader and it displayed error code PO135. Where should I go from here? Thanks

Hello to all - I have a '97 LS400 with 115,000 flawless miles. However, recently the check engine light has pemanately illuminated while the engine is running. All the fluids are OK and the engine sounds and performs perfectly. Would appreciate any and all advice... Thanks
