If your car is hesitating in lower rpm’s, AFTER it has warmed fully, it’s probably a bad O2 sensor. You can test it by simply unplugging the electrical connection to the sensor and drive the car(make sure it’s warmed up). The check engine light WILL be lit.
A cheap Bosche sensor can be found at your local parts store for $50 or so and works just fine. I believe Honda wants $200+ for their sensor.
True. True.
Buy the Bosch sensor at AutoZone or your favorite local auto parts store for about $30.
do you have the bosch part number?

SerialOne,
I recommend just going to WalMart. They have the Bosch O2 sensors. In fact they have the Universal fit for $42Cdn. and exact fit for $72Cdn. All prices are plus taxes obviously. Just say what car you have, and they’ll pull it out of their computer.

what needs to be modified on the O2 sensor to make it fit?

With the exact fit, you just unplug the old O2 sensor from the connector, and plug-in the new one.
With the universal fit, you have to cut the wire from the old sensor, and solder in the new one. You only have to deal with one wire.

If you have a wire cutter/crimper you can save the $5 or whatever and get the universal O2 sensor. You don’t have to solder anything. The universal sensor has a couple inches of wire coming out of it for you to connect to the wire from the car. Make sure to put anti-seize compound on the threads before you put it in.
02 Sensor
Where is the O2 sensor located and what’s the removal process? I have a problem after sitting at idle for a long time the RPM will jump up and hit about 1500 and then go back down. Kinda pisses me off. Thanks

MAN,im glad im not the only one with this prob. When i sit at idle, the tach just bounces up and down, down to almost 0 feeling like its gonna cut off, then sometimes it will idle fine at around 1,000k, when i take off from a stop, i get serious hesitation and jumpin, whats goin on, hopefully its just the o2 sensor and nothing else

for your problem i’d do some diagnositics… sounds like something else is wrong.
Same same same… I have this hesistation too… Something I will definentely tryout. Thanks BTW, if I do code test, will it come up? Also Ive noticed that with the A/C on the car really is gutless, is this inherent with al tegs or just mine? I know that the A/C uses a few horses but to make like this? :shy:
hesitation
I think I’ve got this problem too. When im driving my car will go fine, then hesitate at about 3000rpm, and then go strong all the way to redline. I hope the O2 sensor will fix this, I already tried replacing the plugs and wires and that didn’t fix it. But hey, at least now i have Bosch platinum +4s! 
Sean LS: My teg drives strong with the AC on, sounds like you may have another problem…

Sometimes my car will dip down to below 500 when i’m idling, and sometimes it’s fine. The engine bogs(?) a little if i launch at too low revs. If i launch higher it seems to be fine. I also need to fix my clutch and maybe that will fix that problem. but what about the first one?
I had the same problems, and searched everywhere and everything to find out what the problem was, until i came to this thread. I have an auto, so launching at different rpm’s isnt an opption (unless i purposely like to **** up the torque converter), so i was always stuck with bogging down when coming from a dead stop. I got it fixed for $50, and the engine works perfectly, no hesitation. I also, at the same time, got a full tranny flush for $30, and am happy as ****. Thanks guys.
I recently began having a similar hesitation that would occur between 2000 and 5500 rpm(approx.). I thought it might be the O2 sensor again but it happened whether the engine was cold or hot. It seemed to happen more severely after hard acceleration. I started poking around and found wet oil on the spark plug boots(that insert down into the cylinder head). One spark plug’s terminal was actually wet!!! So I cleaned it all up and torqued down the valve cover to be safe. It drove perfect again. But after a few hard runs, the hesitation returned but less severely. I’m going to guess those 4 little ring gaskets need replacing.
there a snap to replace i did it when i painted my valve cover i think there like 2 bucks each 
i get shitty gas mileage, and ive given my car a tune up getting around 180-200miles a tank
My car hesitates during idle too, really annoying and car shakes a lot. If I was going to install a new O2 sensor where and how would i put it in?
Thanks

well i checked with acura today , told them my prob and asked them if it could be my O2 sensor and they said acuras sensors hardly ever go bad and if somethin was wrong the check engine light would come on…guess ill try the next step, the distributer cap
Yes, the O2 sensor does go bad. I don’t know what they are talking about. Mine went at around 175,000 miles if I remember correctly. There probably aren’t actually that many Acuras coming into the dealer with that many miles so they probably never see the O2 sensor going bad, or rarely if ever.
Also, a bad O2 sensor will not give a CEL. Unless it fails completely. Mine didn’t. Easiest way to check it is to take it out or just unplug the wire. It will give a code but if the problem was with the O2 sensor then your car will run without the hesitation. HTH

ryuyszh…did the o2 sensor help your hesitation completely and when was your car hesitatin…let me explain what mine does, ill take off from a stop…it will hesitate…actually today when i left work i took off in first, it was fine, then i put it in second and it hesitated so bad it jerked me foward…hard to explain but anyway it also does it if im just drivin in fourth gear, ill press the gas and it will hesitate and then go…i really hope its my o2 sensor for real
