Symptoms:
If the Toyota 1.8 l engine is warm, the idle is under 800 RPM's and it simple dies. But of course it starts up again..

Did a diagnostic check, all OK. No lights on the dashboard.

Task completed;
- new battery
- checked alternator, output plus 30 AMPS
- new Wires
- new spark-plugs
- new rotor and cap
- vacuum on thew fuel line is good
- 3rd gas fill with STD fuel cleaner

Runs great above 1000RPM across the spectrum with hick-up or burp?
Any idea how I can fix the idle, or is there more of an issue?
TIA

thanks Roy,
I will get somehow a car manual and check those three items.
The last owner told me it was sitting almost a year, I check the air filter and there where no kriters in it all clean.
