Thanks Trevor, the SC300 has one ignition coil?

It is such a commitment just to pop the plug wires off this car..

Hello,Greetings guys,
I just acquired a 1995 Lexus sc300 with approx 123M

The car was idling really high when starting up. Really impossible in the AM. I see this is a common problem.

Then suddenly one night it started missing from the first turn over. (it was raining BTW)
Really hard to keep idling at stand still,
Feels like a constant misfire. Like a plug wire fell off.
I have managed to get the throttlebody off so as to get to the idle speed control valve(22270-46080 ).

I cleaned the Throttle body and idle Speed Control valve. Didn't fix it.

BTW: the cabin smells like burnt electrical radio smell.

No check engine codes

Could this erratic misfire point to the caps in the ECU?
