2.2 L LN2 I4

For 1992, the 2.2 received multi-port fuel injection (MPFI), replacing the TBI version in the J-body cars and increasing power to 110 hp (82 kW) and 130 lb⋅ft (176 N⋅m) of torque. In the L-body cars it was converted straight to Sequential Fuel Injection. In 1994, all 2.2 L engines were updated to sequential multi-port fuel injection and power increased to 120 hp (89 kW), with torque increasing to 140 lb⋅ft (190 N⋅m). The MPFI and SFI versions produced enough power to allow the 2.2 to replace the old Pontiac Iron Duke engine as the 4-cylinder offering in the S/T platform trucks and A-body cars. For 1996, it became known as the Vortec 2200 in the S/T trucks. For 1998, the engine was revised for emissions regulations and became known as the 2200. This revision lowered power to 115 hp (86 kW) at 5000 rpm, and torque to 135 lb⋅ft (183 N⋅m) at 3600 rpm. The engine was discontinued in 2003, replaced by the 2.2 L DOHC Ecotec engine. Although it displaces 134 cu. in, the 2.2 L OHV is still commonly referred to as the GM 122 today, and has been reputed for its simplicity, reliability and ease of maintenance in the J-body cars and S-Series trucks, and a few L-Body cars. The 2003 model LN2 is equipped with secondary air injection.
