1994 Ford Ranger 2.3
1994 RANGER 2.3, 5 spd, `190,000 miles, good condition. Started getting check engine light intermittently and runs rough with no power when light is on. OBD II reader with adapter for OBD I says check connections when try to pull codes. Older OBD I reader gets nothing so apparently a problem but where do I check first? Light and running rough may occur whether cold or hot and may occur several times in 20 mile commute. Without ability to get codes what is likely culprit - MAF, EGR, TPS?
