02 highlander
so this is more for the toyota techs, i have a 2002 4cly. highlander that i have been having the check engine light on for a while. i have checked the codes and got got codes for the o2 sensors and replaced them all, i now get it feeling like it is about to fall on its face, feels like it is missing and only when i put it in neutral it stops feeling like this, also i put the test for the codes the other day and it had just 4 blinking symbols for catalyst monitor, heated catalyst monitor, oxygen sensor monitor, oxygen sensor heater monitor, im not sure where else to look or find my problem. any help would be helpful, also i have been looking and cant find a diagram of the eletrical system so i can start tracing the wires better,
thanks.....
thanks.....

i have used denso... i have replaced all 4 now, and im thinking that the power going from computer to the heater circuit is the issue, but im not sure where or what the power should be.
