Hey guys, I am officially part of the Honda family again. After my 96 Accord I bought a 2001 BMW 325. I now bought a 92 Prelude Si 4WS today as a project car!!!! It has 155K mile but it still pulls VERY strongly!!! I am VERY surprised. Body is in good shape and the interior is in great shape. I picked it up for $1800
Now for the bad news. After driving the car around for the day, I noticed that the rear right tire was low. RIGHT when I was about to go to get it filled up I noticed that the 4WS light on the dash panel light up. I turned off the car, let it sit for a few minutes, then turned it bad on. The light went away. Then I filled the tire up (only has 12 psi in it

), turned the car back on and the light came on again. I drove the car back home. Let it sit for 30 min, turned the car on and the light was gone. I went to fill it up with gas, turned the car off, filled the car up, turn the car on again and the light is back on.
Anyone have a similar problem like this with 4WS?? Is it bad??? The car handles fine, no unusual noises coming from the car. Any ideas what it could be??
Your help is GREATLY appreciated!!!
