Report: Hesitation Due to Carbon Deposits in Intake System
Mitsubishi Eclipse Problem
Model Years Affected: 1990, 1991, 1992
A hesitation/stumble or driveway dieout maybe noted when starting the engine cold. This can be caused by carbon deposits built up on various intake components - air flow sensor, air intake hose, air intake plenum, and intake manifold. These components should be inspected and cleaned as necessary. If heavy deposits are found on the intake valves the cylinder head may need to be removed for proper cleaning.
Was periodic but continuous now. Studders after idle speed ican press gas pedal to try keep from dying or to gain speed or to stop the hesitation
