Answers :

The engine can not idle right for vast reasons.
wont idle, does that mean
1: stalls.?
2: or wont regulate, hot.
3: or both.
So , no DTCs, no cell lamp glowing , running?
you replaced some very expensive parts, by guessing?
checking fuel pressure costs $20 for the tool.
do you have a $50 scan tool? if yes, you can scan all sensors.
and see if the sensors all look good. do they?
did you buy a used maf ,or new suzuki maf $$$ or the china clone.
most of the clones are no good.
best is , used, and from Cardone.(rebuilt by pros)
the China clones , read wrong, the ECU does not know its wrong
because it is not stuck at 0 or 5v. so assumes its right and is wrong.
with a scan tool you can see the MAF read wrong. do you?
what i do is plot TPS angle, RPM and MAF output and log that.
then at home read the values.

the #1 reason for stalls is leaking EGR. ever clean and service it?
