okay...so...i got my 93 sc400 last year. $2,600 and 130,000... at the time it needed a new altenator(2of the3 bearings were bad) so i replaced that and the battery. the serpintine belt and tensioner, plugs and wires (NGK premium platnum plugs) and recently did tranny flush and used 10 qts of toyota dext4,needed lower control arms- TOYOTA SUPRA TT ARMS and replaced struts-with TOKIKO'S...she handles like a dream and i upped the wheels to some light weight 17" with 235/45/17Z rated tires....now here are my problems...1)the check engine light is on and when me and my buddy try to see what codes its throwing back the damn car doesnt tell! Could it be a fuse burnt out? previouse owner swapped radio-has an alpine 3 disc in dash changer-which skipps when i hit any bumps-even with new cd's in there. i think the aftermarket altenator is trash or there is a wiring problem b/c when lights are on and i signal, the PWR light flashes a little...basically i have same problems as every1 else...instrument cluster is dark amd my TRAC light and TRAC OFF/CHECK ENGINE lights are always on. i need a passenger door panel ASAP!!!!like yesterday! amd i want cloth/manual seats so i can sit lower (i am 6'4) oh yeah! when the headlights are off the temp screen lights up but headlights or park lamps on the screen is not illuminated. oh! forgot to mention i charged the a/c 3 times this summer already! it goes away within 36 hours and it gets hot in there when i run it. and why cant i find the online service manual for this damn car!?!? if anyone knows where i can get one other than a lexus dealership for 300bones please tell me!
