hesitation problems

I just recently had my fuel system cleaned out, filter replaced, and replaced the plugs and wires (Ive heard you shouldnt do this) and my car is still hesitating when I come off an idle. It runs almost perfect from a cold start. I saw another thread by a guy that had an older z24 and it was the same exact thing, he had to reprogram something in the car to get the cylinders firing right and the fuel flowing normal. I also just recently got 2 codes, O2 sensor (plug wires?) and heater circuit(?).
If it is the plug wires, where can I get OEM or atleast some that will work correctly? Thanks.

02 sensor is not plug wires. and it will cause a problem with the fuel air mix.... it is located on your exhaust

no i read that bad plug wires lead to false codes being thrown...and i heard there was two on the 2000 cavalier...one in the exhaust manifold and another behind the cat, but I keep hearing different things, and the
only way to fix the o2 sensor is to buy another one correct? there isnt a fix like the tcc solenoid thing or whatever? how would i know if that problem occured? if i can remember when i got the code read it was like P104 or something.

its very important i get this fixed as i live in winterpark, fl and drive to work everyday to the int'l airport, which is close to an hour away.

anybody?

A Bad O2 sensor code means you have bad O2 sensor. Replace them both, its nothing but a few turns of a ratchet. And if you ever "fix" the TCC Solenoid by unplugging, you don't need to be working on cars, ever.

Not exactly what I was talking about - what I meant by fix was to "remedy" the problem "temporarily". But I understand the internet is your place to act like a hard ass.

As to the other person who actually gave me some insight without acting like a fool, thank you. I'll go about my way and replace the O2 sensors and hope it solves my problem since that question wasn't really answered.

ok wat else would b the problem of accleration hestitation and knocking of something under hood if u changed wires and plugs and didnt fix could it b a coil pack doin the knockin and crap

HEY, DID YOU EVER FIX YOUR PROBLEMS AS I HAVE THE SAME. ANY COMMENTS YOU HAVE WOULD BE APPRECIATED. THANKS!!

if your engine is nocking youirnot fireing right or egine is bad, if you have a O2 code REPLACE IT

YES I got it fixed, check ur coil pack thats wat was wrong with mine, even tho i still beat a jetta while my coil pack was bad, no they made me change the plugs wires and the 02 sensor and the throttle sensor and it was really the coil pack so check that also.
