So is the misfire on idle or a certain rpm?

thanks for replying, yes just sitting at a light it keeps missing, and when you

are accelerating up hill it will start missing-problem happens once vehicle warms up.

Hello to everyone. I am a new member with my first Lexus. A 1993 LS 400 bought through EBAY in Florida. As you know this is a wonderfull automobile. But soon after I received the car it developed a miifire at low speed then at idle and finally at freeway speeds. Jerking on the slightest acceleration. Esp. on an incline. Could barely acheive 40 MPH on a hill. The missing was intermittent but very frequent.

I had some great advice from a Forum member as to where to start. I started with a tune up. I found massive amounts of corrosion on 2 plugs and inside the right bank coil wire and dist. cap terminal junction. Replaced everything and my "new " LS 400 is running fantastic now.

I just wanted to pass this info. on to the forum. And say thank you to all who post. You advice was invaluable to me. walt
