99 s10 poor top end power

[metallica21156]

i have a 99 with a 5 speed in it. the other day i went to do a burn out and it was sad. held it to the floor with clutch pedal in and revved right to 3000 and then after that it took awhile to get close to red line. i never even made it cause i gave up waiting. sometimes while driving i'll hit the gas and feel it stumble and then go. it just seems like it has no top end power. it has 122,000 miles, just cleaned egr,mas airflow sensor, used but know good working o2 sensors. what else could cause this? no ses. i have a scanner so if someone knows what i should look for let me know. i also have gotten a 02 sensor heater issue on all 3 o2 sensors at the same time. then 2 days later i got it again on just the to front o2's. unsure if all this means the computer is dieing. i also own a 98 with auto trans and seems its 10 times faster then this one and it has 152,000 on it. just did oil change and had no metal.

first time i tried it with the truck. just bought i 2 weeks ago. even at highway speed. drop it to 3rd gear revs to 3000 and then dies. when you drive it, it feels like you let off the gas. i dont know if computer is pulling timing or what. gonna change fuel filter and see if it helps.
