Issues with my 2.5RS need some help

[Vertigo101]

Hey guys I just had my muffler changed from a magnaflow back to the stock 2.5RS muffler and my car is still stalling when you start it and dies right down and stalls if you don't keep the RPM around 2 1/2 or higher.

I also noticed that while driving down the road every thing seams fine and dandy and I got some quick acceleration compared to my last car but once I hit 4 RPM its like the car can't climb any more and gets stuck.

Any one know of what I speak? I think I may have a bad 02 sensor, spark plugs or fuel issue.

I am not good with vehicles so any assistance would be great

Check engine light?

Check engine light?

not sure its not on. I think the last owner took the light out but I am unsure.

I am going to have one of my dads friends check it for free this week end

Does the light come on with key on engine off? This is bulb check. If not then its disabled. recommend scan for faults anyway and go from there. How's cam timing? Any other known recent work done?

well as most of you know I bought a 2000 Impreza 2.5RS from a forum member last summer.

I had two new rocker panels made and installed as well as having all the breaks fixed. Also had my rear fenders re painted because of rust issues. I had a wheel bearing changed.

that's about all I can remember. I will ask Iboc my brother when he is awake.

MAF Sensor? I'm not sure if the 2000s have one, but sounds like what happened when the MAF on my '97 was unplugged.

2000 was a map sensor....
