      the base engine; Wikipedia's Family II article gives LE4 to the Sunbird for 1992–1994, and its Sunbird article dates the change from throttle-body to multi-port injection to 1992; 1994 also from the NICB 1998 manual (2.0L I-4 MFI, no RPO code); no Cavalier kit page prints it

    This page aggregates every documented appearance of LE4 in the Pontiac reference. Confidence and citations are shown per application — the same code can be better documented in one year than another.
