Discussion summary

idle drop

Driver of a 1989 Prelude Si 2.0 says the car sat for an unknown time; it runs but on start almost dies. Idle is about 750–850 rpm but drops below 500 rpm or stalls when the clutch is pressed. The poster checked vacuum hoses and reports new NGK plugs, 9 mm wires, an MSD ignition, performance intake, and that rotor and distributor cap look good; fuel pressure reads normal though the fuel filter hasn’t been replaced. The poster asks whether the transmission could be the cause.

Reported outcome: The poster did not report a fix or resolution.
