Help please!

Ok, so I know you say Bosche O2 sensors are probably a bad idea, but I think that's what I'm going to get. It's going to cost half as much as one would be from Honda.

Which brings me to my next question... I'm getting it from Auto Zone and they said they have two different ones before the cat. One is 13.9 inches from the ceiling surface to the end of the connector and the other is 17.6 inches. The 13.9in is 54.99 and the 17.6in is 69.99. Anyone know which one I need?

I have a 92 Accord EX with an F22A6.

Either one should work as long as it has the proper connection.

What it is, is that depending on the manufacturer they try to make it fit multiple applications. Some make it so they have a longer wire so they fit more applications where the O2 sensor is further away. That's all.

EDIT: Oh and stock O2 sensor wire is less then 12" long if I remember correctly, something closer to 8"...

My bf put in the new coolant temp sensor and o2 sensor last night... Didn't help. I was very hopeful that this would solve the problem.

I want to start cheap and work my way up - what else should I check??

do the RPMs jump at all?


so if you floor it, it'll acclerate fine. but if you just drive normally, it'll start missing?


sounds like a timing issue to me

Change your fuel filter. unless you alredy have. Then check the EGR ports and exhaust flow out of your muffler. A clogged exhaust will make the O2 sensor see things, and sometimes cause it to send a fault code. There are threads on here with pics for the EGR ports. Just click search thread, and enter EGR you will see all kinds of related threads.

I'll just give you a list of things that I would check out (not knowing what you have already done).

Clean out your EGR valve and EGR ports.
Check/change spark plugs, make sure they aren't fowled up and gapped properly.
Check spark plug wire resistance, replace if necessary.
Replace your fuel filter.
Check your fuel pump.
Check your timing.
Check rotor/distributor cap for worn or broken items.
Check/clean your fuel injectors.

My Mom's Mazda was doing the exact same thing as you are describing, we replaced the fuel filter and cleaned the injectors and it cleared it right up. I'm not saying that this will fix your problem, just that it sounds similar to what we were having a problem with.

Yes, the rpm's will jump sometimes. It's almost like it's shifting into a lower gear. It'll jump, then it won't accelerate unless you floor it. If you don't floor it, it will kind of sputter/hesitate. Sometimes letting off the gas for a second will help, but sometimes not.

What will I be checking the EGR ports for exactly? If you haven't noticed, I'm not very knowledgable when it comes to cars. I try though... I'll search for the related threads.

Thanks for the help everyone.

member radiuslight has one with pictures posted yesterday titled egr valve and ports with pics. good place to start. look at his profile, and click on threads posted by this user to see a list of threads. you'll find it in there.

Just for a little more background info, I found this on Honda-Tech. This guy explains it a lot better than me. I'm having pretty much the same issue...

Here is the entire background. For a month or more, the CEL seemed to come on after about 10 minutes of cruising at the same speed every time I drove the car. When the car was turned off and back on, the light would be off, but it would return under the same circumstances time and time again. Otherwise, the car seemed fine.

Now, the CEL has not been coming on. But the car has developed what appears to be a random hesitation/loss of power. I can only describe it as similar to what happens when your car is in too high of a gear at too low a speed. It seems to happen most in 1st and 2nd gear when you are accelerating moderately from a stop. It appears to be RPM specific because it always clears up higher in the RPM range (above 3500-4000 or so). It never occurs under WOT conditions.

Thanks 93accd, I'll look for that.

check the distributor. i know my tach jumps. and its the ignitor or the external coil going bad. sometimes it even cuts off in the middle of traffic.

Ugh ugh ugh... Cleaned the EGR valve this weekend, but it wasn't very dirty, and my car still runs like junk. I guess it could be the EGR ports, so we'll see. I have to wait until my bf has some spare time to look at it. He keeps trying to convince me to just sell it and drive his extra car, but I don't wanna let it go. lol. I think he is just VERY tired of working on it for free.

im havin the same problem but mine chokes when u give it gas

You could definately have a clogged converter if it chokes even when you give her the gas. Could be blocked badly. My ex's oldmobile had an inner part of the muffler come loose. Sometime when you hit a bump it would block the exhaust and bog down. Look for a slightl higher temp gauge when it happens, thats a good indication of blocked exhaust.

Will a hole in the flex pipe cause a loss of power (like running on 2 cylinders)?
