Idle Problems
An engine needs 3 things to start:
-Proper air delivery
-Proper fuel delivery
-proper spark delivery
So... besides the obvious question of: How much fuel is in the tank???
There are other checks:
-Pull a spark plug. Is it wet with fuel or dry? Wet = flooded. Dry = no fuel.
-Pull a spark plug wire and check for spark when cranking. No spark = check ecu power.
-Check all sensors & connections. The main sensors affecting fuel delivery: CHTS and AFM.
-Open FSM and read.
