pelican made me do it. I just did a search on stumble 4000rpm and noticed alot of guys metioned the o2 sensor could be bad and a quick way to check it was to just unplug it. I did, and the car ran 99% better. As the rpm's hit 4000rpm it would cough, sputter and generally make NO power. Then if you stay with it and fight thru it would start to clear around 4500rpm then take off like a rocket. It was worse when cold but still did it warmed up. The last 1% improvement was disconnecting the huge gold vacuum diaghram under the intercooler. That seemed to cure the last little bit of jerkyness the car had.
