I'm having a small problem with my LS 400. The engine warning light and the trac light come on and off sporatically. And when they do the engine will sputter a little like its not getting fuel. It doesn't happen all the time but lately it's becoming more common. Any idea's?

 

Your 1991? How many miles logged? How dirty is the engine air cleaner? Services prerformed lately?

 

In the past six months I have had the timing belts replaced, water pump, and the Lexus dealer has replaced the plugs and new ignition wires. Its got a total of 108,000 miles. The air cleaner was replaces about a year ago.
