?? on o2's
 

How bad would my car be running if i had 2 bad o2 sensors??? i just installed headers yesterday and it feels like its not running right at all

Probably feel really sluggish and your mileage would blow. You'd eventually throw a ses light if even one was actually bad.

did you make sure that you didn't crack a plug during the install? you might also check to make sure the plug wires are all the way on the coil packs

^^^ What he said, check the plugs for tiny cracks and check the wire connections. if you arent throwing a front O2 code then your o2's arent the cause of your problem.

to answer that question, since when I first installed my LT, I wasn't paying attention and hooked up the rear 02 data cables to the front 02 sensors (as if i had no front 02's the entire time, so the computer is running off of a standard, generic number) it ran sluggish, and after about a week or so, it started back firing like no one's business because it was dumping so much fuel into the lines.. i corrected the problem, and it is much more responsive

just changed out the o2 senors and now it runs alot better!

How did you know? I want to check and see if I did this. Autozone told me I had a bad front and a bad back one. Which is dumb, because I should have two bad back ones and no bad front ones, you know?

Which is the front ones? Bank 1? Or, are the banks from left to right?

P0134 (No activity; Bank 1, Sensor 1)
P0134 (CKT No Activiy; Bank 1, Sensor 1)
P0155 (O2 Sensor Heater Circuit Malfunction; Bank 2, Sensor 1)

bank one sensor one is the driver side font one and bank 2 sensor 1 is the pasanger front o2 i threw the same codes so i went out bought 2 new corvette o2s cause i hear they handle the heat better so if i were u i would do the same thing u will tell ur car runs alot better and ur gas mileage goes up!

I bought some and put them in like 5 months ago. My mileage didn't improve like I'd hoped it would. Really don't notice any difference, but at least I have some new o2's :eyes:
