Question about 1991 Lexus LS 400

1 Answer

My 1991 Lexus LS400 will crank and will drive but will not accelerate at times then it will do somewhat fine on the highway not going over 65mph, in the city it will not pick up and it cuts off when at a complete stop. Once parked I see some coming from the bottom of the car, not the engine part but the part under the seats.

Check and clean connections in your fuse boxes with an electrical cleaner.Change burnt fuses and ensure there is contact on your fuses. Check connections of your crank and airflow sensors as well. Clean the sensors first and if problem persist ,replace with new ones. Then take your car to a diagnostic technician to reset and check other technical problems with the diagnostic machine.

Not too bad. Not much room, just enough to drop the starter. It is probably easier to go up through exhaust if you can get your exhaust shield off the manifold .

Lexus LS400 with 80000 miles. Bpught is used and ever since ther steering wheel feels very loose is this the norm maybe im used to driving a van in which the wheel is much tighter? thanx for your help


Hi,
Both your Van and your Lexus have power assist steering. So the "feel"
will be somewhat different. How quickly and easily the "Assist" helps varies. The Lexus is an Luxury car.It is designed to make steering easier.
Less effort needed by you turning the wheel to turn the car. So you were right in your diagnosis. The Van will have a heavier feel.
Enjoy the ride.
