I just reset my CEL after getting these 2 sensors codes.

Are these replacements easy for a low-level DIYer?

If so, any directions or suggestions?

Car seems to drive fine. What can I expect if I don't replace them.

Thanks,

The throttle position sensor has to be calibrated in place. You'll need the Haynes shop manual to do that, unless somebody wants to post the procedure for you. The o2 replacement is straight forward.

 

I just replaced my throddle sensor, big differance. I get alot better gas milage now.

 

How much did a new one cost and are you sure what you replaced is a throttle sensor???

 

yes i am sure. It is the black sensor on the back of the thoddle body. I have the old one as well, so i amsure of it. i think it was around $300 - $350. I am not too sure cause i had other things i got fixed on the bill. It is between those though for labor and everything.
