ls 400

Hello everyone: I currently have a 90 LS400 with a mysterious code 42 (speed sensor 1). I have replaced the speed sensor, instrument cluster and ECU with no avail. Current symptoms are: Code 42 (O/D light blinking) Dead speedometer Dead Odometer Dead trip meter Gasoline smell Very sluggish...

Yes basically I have a 1999 LS400 basically stock w/ 126k and I kept the car just because. Just started cleanning it up - put a new 1000 amp bat in her and cranked it up. Been doing this (starting) every month for a year. I have had the car since 2003 (43K) I plan to replace the timing...
