Question about 1991 Lexus LS 400
Car also seems to kick in and out while accelerating like it is missing or not running on all cylinders.
Lucas fuel injector cleaner in the gas helped the acceleration a lot but didn't solve the stutter at the lights and while accelerating
I'm going to try changing the plugs, plug wires and possible the distributor caps (there are two). I did the plugs and caps 80,000 miles ago.
I'm thinking the plug wire might need replacing now at 255K.
I had the same issue with my SC400, it was due to low compression in one of the cylinders, due to a leaking head gasket... I was in the process of swapping out the engine for a new 1uzfe, so it wasnt a huge problem, I had been expecting it due to the fact that I had 301,000 miles on it when I finally replaced the engine last week.
