so here's some backstory before i get to the problem.
-------------------------------
What i have done to the car:
now that that's out of the way, my problem is that when i'm driving, the car has no problem getting through first gear, but once i get into second the engine will bog down and wont get past 3000rpm. i'll floor it and nothing will change, it will just sputter and try to stall. i'm getting OBD error codes 43 (i believe that's the knock sensor) and 77 (i think that's the cooling fan control relay circuit). i have no idea what those would have to do with the symptoms i'm experiencing, but every time i drive and the SES light comes on, those are the codes it gives me. i only noticed the problem recently after replacing the O2 sensors and spark plugs/wires, so unless anyone else has another idea i'll probably start by checking those to make sure i didn't jack something up.
Thanks in advance for any help!
