Okay heres the Question.

Car is at Operating temp, running and there is a slight miss. My A/F gauge is bouncing slightly...(back and forth).

Now at axactly the same time, when I get a miss (I can hear it) my A/F gauge goes lean.

Question: Is it going lean cause of the miss? Or is my 02 front 02 sensor shot and making it go lean and miss?

Make sense? I changed my rear 02 a few months back cause it was toasted.

Plugs,wires,coil,CAS, have all been replaced. I think its the 02.

Enlighten me.

come of...wtf?

noone?

well first things first, fuel spark and air are the main factors in missing. If coil wires and plugs are new, check your fuel filter, run injector cleaner, air filter, coolant temp sensor, iat, etc, it could be numerous things.

Yeah, coolant temp sensor. I know it sounds stupid but get it read and make sure it's operating properly. That's what was wrong with mine. Also make sure you gapped your plugs right.

Also changing your rear o2 sensor won't affect how your car runs, that's there only to tell your computer that your cat is working/exists. You could have put a resistor in one of the wires and not had to spend $100 on it.

So how does the car run on WOT? You do know that while normal driving conditions the A/F gauge bounces right? If you are misfiring, you should be able to tell when you are WOT.

I do know how the gauge works!:P WOT it goes full rich...let off gas -it goes lean...under normal sped it bounces.......

Anyways, I haven't replaced the fuel filter...where is it? and the coolant temp sensor? I don't have any CELs but I do have my Coolant overflow light on...I just think its shot because the level is good.

So how does it run on WOT? Does it misfire through all rpm ranges? Have you checked your timing as well? Because didn't you just do your t-belt due to water pump?

No, It only misfires in the low RPM...800-2800rpm.... sometimes it's bad and now I was just out cruising and it wasn't bad at all....Fuckin car.
I don't think it's the timing for that reason. It' wouldn't be good and then bad would it?

So you also know that blinky A/F gauges are not accurate and read off a sensor that has a limited range monitoring?

Try putting a meter on your coil pack.

yes....not accurate, but at least it displays the reading the sensor is getting.

I'm thinking that it may be the coilpack.....hmmm....Going to the shop RIGHT NOW!

If you need a coil, PM me.

Thanks man, but it turns out one or my spark plugs was cracked. I figured it wasn't them cause I had just had them out to gap a week ago. Oh well. Fixed. Idles normal. I love her again. lol


Thanks Guys!
