My problem is similar. When I first start it, or when I let it idle for a while, it will run rich (and fast). But when the exhaust is warm, after I drove for a while, it gets slow on acceleration. If I push the gas down to pass on the highway, it acts like it is starving for fuel leaning out and the "check engine" light comes on. I am going to replace my oxygen sensor this weekend, see if that fixes it. I will post here on monday.

I had this problem too.

I checked all the usual stuff (timing, plugs, wires etc). I do have a Air/Fuel ratio guage installed and noticed it wasn't acting like it had a few weeks earlier, I replaced the O2 sensor and all is fine.

No more check engine lights when passing on the interstate.
