Default Idling weird, won't start

My 1995 SC300 won't start or idle correctly in the mornings,the car will idle at 800 RPM then jump up to 1200rpm or it will completely not idle at all. I checked to see if it was my ECU and there's no issue, but when I try to start my car at like 2:00 in the afternoon no issues. It is a little bit colder in the mornings but not extremely cold. Any ideas or advice on what could be causing these issues?

Most would say ECU capacitors have failed and causing issues.... I would say rebuild the idle speed control first, then move on to the ECU or possibly other electrical gremlins.

Check for air leaks in intake; hoses, connections, etc. Check IAC valve.
Check MAF
Check two wire temp sensor in head.

If you have one of the custom readers you can check temp reading, afr, etc and see if on cold start you see anything. I have one somewhere but have t used it in years.

Stuck in Park as in unable to turn it on? Or it's refusing to release from Park? There should be an override button right by the shifter where you can use a flathead screwdriver and push it down. This will release the transmission from Park

as tallyho said just pop out the cover for the release and insert something to release the park lever. But it sounds like you have a power source issue. Check all the large fuses in the engine bay and in the left kick panel.
