'95 LS400

Congrats!!! I just had mine cleaned as well. I have 231k on mine and I was told that this was probably the first time it had been cleaned! It had a lot of buildup and my idle was at 400 rpm's when I brought it in. I got it back and it is now idling at ~600 rpm's. What a difference in power! However, I am still having problems with my power steering.

It has been a rough few weeks on dumping $ into the car.

Heater quit working when idling...will work when driving: common issue just replaced reservoir cap and seems to be working - Fingers are crossed!

Alternator went out, oil had dripped from the valve cover and coated it - easy to replace: Great info on the site on this - Thanks Everyone for the posts!

Replaced battery

Valve cover gasket replaced 15k ago and leaked again, mechanic would not replace due to warranty....BS

Power steering intermittent...Troubleshooting right now

Check engine light on: TPS sensor - mechanic replaced twice - mechanic says it is a problem with a board???

Thanks. I am the 2nd owner and the filters were probably not cleaned. I have found a lot of threads on the power steering solenoid filters and will try to clean tomorrow if I can find all of the details on the procedure. Any recomendations?

I have a '95 LS400 w/231k that has started to have several different problems and have fixed most with the info on this site!!! Thanks Everyone!!!!!!

I had my ps go out the other day and on my way to get it checked out it started working when I was under heavy exeleration. I have found that this will enable/disable the ps.

Any ideas???

I have a '95 ls 400 w/ 131k and my ps has been intermittent as well. However, I found what will cause it to go on & off. If I bring the car above 5,000 rpm's under heavy exeleration, this will disable/enable the power steering.

Not sure if this is related, but I am looking to see if this might be a vacuum valve problem that????
