ya.so when im going to accelerate harshly in my 92 ssei, it will cut out,sometimes backfire mildly,and produce an ses light.if i baby it for a minute the light goes away. it has a fresh fuel pump,filter,and pressure regulator.the ecm has like 1500 miles on it 2. what the... ?

Have you scanned the code to see what it is? That would help us diagnose the problem.

tryin that right now.got a bunch! 12,15,18,21,22,31,34,42,57,58,66.

Holy cow..

15:Coolant Sensor Circuit
18:Cam/Crank Error
21:Throttle Position Sensor (TPS) Signal Voltage High
22:Throttle Position Sensor Circuit (Signal Voltage Low)
31:PRNDL Switch Circuit
34:Mass Air Flow Sensor (MAF) Circuit
42:Electronic Spark Timing (EST) Circuit
57:Boost Control Problem
58:Security System (Fuel Enable Circuit)
66:Low A/C Refrigerant Charge

I'm going to say a possible electrical issue. Check ground busses and battery cables for corrosion. One of the gear heads should be in here soon to give you a better answer.

crazy right! drivin me nuts.i soooo love this car.have only had it for a month.my girl keeps tellin me to sell it,but im soooo convinced that i can figure it out and have a sweet machine. just need some help.

If you have the ability, I would also try clearing all those codes then checking it again after a drive to see what comes back.

how do you clear the codes?

I believe if you disconnect your battery for a while it should clear the codes. Something like 15 minutes should do the trick.

cool will try it.thanks. let ya know in 15 or so.

ok,58 was the code after i pulled the battery cables for a couple hours.security? what do i do about that?
