To answer your questions, it’s a 93 Suzuki sidekick is what engine come out of. it’s OBD 1 I have checked for codes and gotten 33 & 34 which refer to MAF sensor. I have put 3 MAF sensors ranging from 150$-425$ no change! I have checked power and ground to sensor solid 12.8 v. I have ohmed wired all way back ECM checked good! Here is a parts list of what I’ve threw at it with ZERO change.
-New EGR valve.
-All new vacuum lines
-New o2 sensor
-New Cold idle control valve
-New Idle control valve
-New TPS
-New plugs & wires ( gaped to 28)

-Checked timing multi times. Timed on 4.
-Checked keyway!
-Pulled engine and rebuilt had block and heads worked and checked
