Thanks for taking the time Pishta,

I was begining to lose hope of getting a reply. No Seafoam here. I will try some other fuel injector cleaner.I will try to buy a rebuild kit for PS pump and fix it myself. There was a code 24 stored but the CE light is not on. TRAC give code 19 and 51.

Hi,

I'm a new owner of a 91 LS400 in large part due to this forum. I'm very happy with it so far. There are some things that the car needs done but I just don't have the money to have a lot done, I can barely afford gas. I prefer to buy tools than pay a mechanic. Here are my questions:

Biggest problem: The car's giving me only 13 mpg (6 km/l) in city. Tyre preasure is maxed out 38 psi but it feels like i'm pulling a trailer. Using 91 octane. What do you think is wrong? Check engine light is ok. Can the Oxy sensors be bad and not show up in check engine? How do I find out if they are bad? I have ramps and can buy oxy sensor socket. All four may need to be replaced? Or front more important than rear? What else can i do to decrease consumption? Alternator?

Other problems:

TRAC light comes on after a couple minutes of driving and periodic humming sound. Is it ok to ignore it?

Very Minor oil leak around oil pan, PS rack area. Oil level stays high.

Very minor oil leak around PS pump, area barely moist. Oil level stays high... ok to ignore?

Sometimes car blows white smoke when started. Not always.

Upper control arm joint a little loose. little play. Ok to ignore for now?

Your advice is much appreciated

I have the same problem, any ideas?

Remove the seatback,

You will see that the plastic covered shaft which is supposed to connect to a spindle but has disconnected.

All you have to do is first get the seatback level. Then insert pliers from the rear, grab the shaft where it is supposed to connect (not the plastic cover) and push it back in...

Done.
