EM1 - CEL went on again...
I just got this code!... again! I'm really sick of this... I've replaced my sensors many times and just put in a new cat
P0133 Circuit Slow Response Bank 1 Sensor 1
P0420 Catalyst System Efficiency Below Threshold
I have bosch sensors, up and down stream and an aftermarket cat, and I/H/E.

You need cel elim...Mine did the same thing same codes...with cel fix it puts the secondary o2 sensor in position so it doesnt read the same as the bank 1 sensor thus making the cel light come on...Hope this helps..

Not sure about emissions..but with the cel light off I dont see why not...Should only need one on the secondary 02 sensor thats in the cat...Good Luck..

Yea, Bosch = garbage. If you wanna save some money you can get the NGK replacement oxygen sensors. I've tried these on my RX-7 and they worked great with no issues.

Re: EM1 - CEL went on again...
Why is it broiled..Cause thats probally part of the problem...you can get a high flow cat from many places or test pipe and replace sensors and add the cel elim and all your problems will be gone....but you need to figure out why its broiled if you dont know..cause if you dont fix that problem its gonna ruin your sensors again and you will be right back in the same position in a month...
