Engine Performance problem
1994 Hyundai Trajet 4 cyl Front Wheel Drive Automatic 71000 miles
My original engine burnt, and was replaced by another G4GC engine. However, the engine light remains on because a senor port on the Cylinder head is absent. Since installing this engine I am plagued with a serious hesitation problem whenever the Air Condition unit is on. The compression reads ok at 240, 240, 250 and 248. The Trottle position Sensor is receiving adequate electricity, and the fuel injection system is functioning properly.
