Hi all, i have a my95 wrx that has just started to hesitate on part throttle and when you pull away there seems to be no power then it will comes back and cars fine for a few minutes. But when you floor the car it pulls fine with no misses does it sound like the maf.

Thanks for any advice

 

could be number things maf, boost solenoid, plugs, coil pack

 

Changed the plugs today gapped to .7 old ones were gapped to .5 cleaned boost solenoid, cleaned maf all the coil packs look good no cracks. I did dis the maf when the car was running and it continued to run badly, but when i plugged it back with the car running it stalled is this right.
