The Automotive Test Solutions iEA Intelligent Engine Analyzer, No. EMI1030, is designed to help technicians identify camshaft timing problems and misfires. Users can detect pressure changes in the cylinders through the spark plug hole, and identify misfiring cylinders from the exhaust tail pipe. The iEA checks cranking, intake and exhaust pressure pulsation, checks restricted exhaust system and checks ignition timing. It converts pressure transducer voltage to actual pressure or vacuum readings, and can be used in conjunction with all ATS diagnostic equipment.
