1.6 16V, 97 ps, 1995, 2doors, 5 manual trans. Vitara. G16B MPI.
for full power, the order below, matters.
good engine, (compression tests pass)
good spark and timed right, base timing good.
then fuel pressure, sure the FPR regulates that but other reasons can cause low fuel pressure, (pump,filter or pinched lines) and the ECU does not know it is low ever, so injects too little fuel if pressure is low.
plenty of air, air cleaner not packed up and choking engines.
next is MAF sensor working right, it reports, air flow, and if under reporting, (even air leaks behind it, called illegal unmetered air , even cracks in the top air pipe, or seals failing there.)
then injectors , under injecting, due to its screens inside clogged (tiny screens 10 micron size) if the car had bad fuel, injectors can packup easy. (try Chevron, Techron injector cleaner in tank)
a melted CAT element inside (honeycomb brick inside it is), if vacuum tests act real oddly or delayed, look here.
The CEL lamp only has 2 wires.
1 is power
the other pin is the ECU, that turns it on with a transistor inside the ECU.
it must glow with keyon, only. or lamp is bad, wires too it or ECU is bad. (some ecu go to backupmode, 10x worse than limphome mode.
backup mode is for dead ECU, and the backup is what I call lawnmower mode, dumb simple, crude injections. and a dead CEL lamp.
you are welcome.
cheers ! to you.
