Hey ya'll. New to the forums. So if this is posted in the wrong spot, I apologize. Please move it to the correct location if need be.

Anyways, I'm having a problem with my car, and I'm looking to see if someone can help me figure it out. I've got a 93 240 hatch with an RB20DET swap. The swap was done by the previous owner, not by me. The car is my daily, and I've had it around 3 months, without any problems until now.

About a week ago, I was driving, and the car gave a sputter. I stopped at a stoplight a little after, and the car died on me. However, it started right back up. Its done this a few more times over the course over the last week. The "Sputter" seems to be getting worse though. When it does it, I get no throttle response. I can mash on the gas, but the car just loses speed. At first it would sputter and catch allowing me to keep driving, but now when it does it I have to pull over and let the car die. And at first the car would start right back up, but now it takes a minute before it'll start again. The car also has an idling problem, where the idle likes to fluctuate up and sometimes down while in neutral. Not sure if that could be related or a separate problem.

Anyone have input on whats causing this? I've replaced the fuel pump with a 255 and it didn't solve it. Have spark plugs ordered and when they get here I'll put them in. If that doesn't work my next things to replace are the MAF and TPS.
