ES_300 Posted September 4, 2007 Share Posted September 4, 2007 I own 99 ES300 with about 102k on it, it was running smoothly until yesterday when CEL and TRACOFF lights came on at the same time. When I put the car in drive I can feel it shaking and stalling. Took it to Autozone and the code came as P0300 for random misfire. I got all the spark plugs replaced today and still having the same problem. I unplugged the battery terminal for about 10 seconds to reset it and then started it again, after driving for couple of minuts CEL came on again and I took it to Autozone to get it checked now I got P0301 (misfire in cylinder 1). Can anybody please help me what the problem can be. Can it be the coil on Cylinder 1 and should I replace it to check if it fixes the problem. I tried searching the forum but can't find any specific details, so I will appriciate any help. Thanks Quote Link to comment Share on other sites More sharing options...
