Hello I just bought a 1993 sc300 with almost perfect interior for a steal I'm looking forward to learning more about these cars

I do have some questions about my particular car

power windows work intermittently I have heard the wiring to the drivers door can become fatigued and cause the erratic window problems

cluster needles and ac panel need repaired where do you recommend to have this done

transmission seems to shift into second real early if you are light on the throttle and will not kick down to first other gears seem to downshift fine is this the nature of the beast or does something need adjusting

i also think I need some suspension work as there are some unpleasant noises over certain bumps
it seems that the dealer is the only source for most parts is this correct

Thanks

Tanin is a forum sponsor and the go to "guy" for HVAC and gauge cluster repair.

Intermittent operation of the windows makes me think it's a dying control switch or regulator, or rails that need lubing. I suppose it could be wiring that's bad enough to occasionally ground out or lose the +12v signal, but that seems less likely.

I second Tanin for HVAC, cluster, and ECU. Cant go wrong with them.

For suspension, first check out the control arms, most crucial being the front LCA. You can put poly bushings into stock arms, or go with something like Figs Engineering.

I fixed the windows the white wire with black stripe was broken in the door harness

the radio also works when it wants any ideas where to start

make sure your wiring under the driver side fender isn't damaged

I went to the junkyard to try to find parts for the SC and didn't have much luck only found one car and nothing I was looking for but it had evo 8 wheels on it so I picked up the full set with tires for $200 they have quite a bit of curb rash but they look 1000 times better than the stock wheels eventually I'd like a set of g35/7 rays but these will do for now and allow me to ls400 brake upgrade

'I am having a misfire under load sometimes it always goes away after driving for a while I'm gonna do plugs wires and cap & rotor and hopefully that takes care of it

KevinSc

I am going to get new spark plugs any recommendations?

platinums seem to be what the factory put in

also cant seem to find a throttle body gasket the only one i saw $60 which seems rediculous

I used NGK plugs (BKR5EIX-11) & wires (TE120).

The OEM throttle body gasket is under $10. #22271-46020.

Well I bought a 1992 sc400 parts car since I couldn't find parts in any junkyards both are pearl white so I will take the best parts and put them on the sc300 since the sc400 has a bad tranny

KevinSc

Swapped the winged trunk from the parts car and power atenna cant wait to get the sc400 front lip on

KevinSc

Installed the sc400 front lip from the parts car
Changed the plugs they were wasted not sure how it even ran and passed emissions

KevinSc

I wanted to take the rear brakes from the SC400 parts car will they bolt up other than maybe trimming the dust shield are the parking brakes compatible
