RB25DET stalls out

[welts12786]

help me out with my RB25DET Series 2 issue. Sometimes it drives great no problem like a champ. Then other times it wont rev past 4000 even on WOT and then stalls out. Just changed my spark plugs taped up my coil pack. Getting spark on all 6. Good fuel. just changed out my fuel filter z32 filter. I got it running good but now its doing this wierd throttle issue. throttle position sensor or crank angle sensor

Could be a bad maf sensor. Have you checked for codes?
