Car is sputtering as i'm about to pull off,idle drops to about 3-500 rpm but if i put it in neutral it catches itself.
i cleaned the MAF changed plugs and still no improvement.

What is your idle at engine working temp?

IACV valve prolly needs cleaning or IACV stepper motor is failing.

idle is around 800rpm at working temp.
i used some redline with premium and the problem seemed to stop,i ran the tank low last week and some particles probably clogged the injectors...

Check fuel pump. Had a wiring issue with mine (SR18DE), car would stutter then sometimes die.
Also try re-grounding you MAF, just google MAF grounding SR20, also check distributor cap and plug wires. (I am still trying to locate a new distributor cap for mine).
