possible throttle prob

[OkcSolarafreak]

Recently my car has had this strange problem. My gears feel like they are sticking but its not a trans problem. Whenever its in first ( its an automatic) it doesnt want to shift to second until i over rev and let off the gas, and than its fine until i try to floor it and my rpm shoot up but my throttle has no response it just keeps going like im not doing anything and wont shift. I replaced the tps and going to replace the maf sensor. Any ideas what the problem might be or solutions would help me out alot.

its a 99 1mz with supercharger( if that matters)

its a 99 v6(1mz), its looking like a open or short circuit from the codes i pulled either the knock sensor, valve posi or the heated o2 bank sens1, im starting to think my computer is going out but im not sure. also i recently added some fuel system cleaner and these problems occured the next day for the most part.

what type of fuel system cleaner did you use? Techron or Seafoam?

[OkcSolarafreak]

used gumout im pretty sure it screwed something up or cleaned it good enough to clog something

replace the o2 sensors, do the knock sensor rewire and then see if your still getting CELs

i did the o2 before cat, the knock sensors are gotta have to wait.

Since you were under there replacing one sensor, you should have gotten the other one too. The sensor before the cat is the hardest of the 3 to replace. The knock sensor rewire will take like 10 minutes.

im on a pretty limted budget lol and i work at autozone so every now and than stuff comes free and i got that an o2 for free. im not sure how to do the knock sensor rewire ive never had to do it before.
