I replaced my o2s saturday and ever since then my car is acting up it is surging while driving and when i push the gas it kinda boggs down what could this be?its almost like i got bad fuel....

 

Was the car or what was the car doing before.

 

Try disconnecting the battery to reset the PCM. Maybe it is tuned to your old sensors, and if they weren't working very well, those adjustments aren't right for your new sensors. Wouldn't hurt to start with a clean slate and see where the adjustments go - maybe it will help. Also see is anyone can scan it or log it for you.

 

it was running fine i changed them cause i was told when you put headers on it burns them out plus my check engine light was coming on after i installed the headers so i assumed they were bad and it seems like as soon as i replaced them with the new ones it started running bad.

 

I disconnected the battery right after i changed them maybe I'll try it again.

 

That sucks - see if you can get a buddy to scan it for you and see what's wrong in there. Also make sure the wires aren't burned.

 

If your SES light came on, did you try flashing the codes on the SES light to see why it came on? Your 93 is the only year LT1 you can flash the codes by jumping the pins in the ALDL connector. Generally a good idea to check the codes before you spend money on replacement parts.

what about bosch i was just told they didnt do well with our cars and thats what I put in it.....

 

Well let's try a different approach - you just did headers - do you have a bunch of exhaust leaks? and are they maybe giving you a problem with a false lean signal to the O2 sensors making your car run rich?

 

did you use o2 extensions? or did you try to extend them yourself by stripping and crimping wire to extend them?

 

did you do long tube headers, did you remove the cat that could be why the ses light is on.

 

No its a 93 Won't trip a ses light no post cat o2 sensors...

 

ok, just throwing out a suggestion. something else to cross off the list of possible things that are causing the problem.
