Did you change the Bank 2 (radiator side) Upper Sensor the last time?
If you did, then per TSB, your EGR could be the issue.

how about stuck off? when i changed my plugs last, i think i may have knocked that smart box thingy under the plastic cover. cause after i changed my plugs, it had no top end whatsoever. then after about a week, it felt like they would come on in first and then shut off right before it shifted into second. Its an ATX.

now, it seems to run fine during colder times like nights and mornings, but not always when its warm out midday.

thanks again for all the help, its been priceless to me so far.
