I take off inlet hose and replaced spark plugs. All finished I start engine at idle but idle is between 1800 and 2200 RPM not stable?

Try cleaning throttle plate on both sides an diac hole with choke cleaner then look for a vacuum hoses off or broken.

Check for vacuum leaks then scan for codes and check fuel pressure with a gauge auto parts rent the gauge
