01 acceleration problem

[Eenie]

Help!

I have a 2001 S with high miles (approaching 126,000) and I'm having acceleration issues. The accelerator only responds within the first 3/4" or so of depression. After that, it seems like the fuel cuts out, and the engine drops to idle speed. Also, as I'm accelerating, it bucks between 2000 and 4500 rpm. I just replaced the fuel filter and spark plugs, and neither helped. It actually seemed like it got a little worse, although that could psychosomatic due to extreme frustration. Any suggestions?

Thanks!

Hello

I had the same problem with my Grand AM, I did the same as you, replaced the obvious parts and still no go. The problem was my MAF. I replaced it and it was fixed.

Hope this helps
