knock on wood, 5 days and the CEL hasn't reappeared yet, weird don't you guys think?

 

guess i shouldn't have said anything....got a CEL today on the way home from work. will get the code read tomorrow and guess start over from their

 

I was going to post before that I had wishful thinking like you, but I didn't want to jinx you Anyways, 99% it will be the same code, and just follow those steps Brian. Just have the car raised, check for leaks etc. Also, I wouldn't change out all those o2 sensors, just the bank2 sensor2 one

 

sigh, was on my way to the mechanic today to get the CEL read and driving down the highway it turned off, frustrating

well im gonna change them when i do my headers as they old....i mean my car is 10 years old so i figure i would do some preventative maintenance while i did my headers.

gonna feel around for some leaks when its not snowing here.....or freezing cold. its 28 degrees right now

 

To know if you got an exhaust leak, simple park your car in a quiet place so you can hear it. Turn on the car, put it in drive, one foot hold the brake, other put hit the gas and rev it up to about 2k rpms and you should hear like a muffle sound or a ticking sound.

On our cars we got 2 warmup twc cats and the last cat in the middle is regular 3 way cat.

So what's your CEL code?

BTW, if you are gonna change your headers, might as well change all of your air fuel ratio sensors and oxygen sensors.I'm saying this cuz i know you have money You will feel the difference.

 

knock on wood one month later, no CEL. weird man....

 

That's weird, but awesome. I hope it stays that way

 

i know def weird....me too. i hope i dont jinx myself by saying that either. i have put like 3k on since the last post to and still nothing. im baffled

 

well, i did NOTHING to fix it but cleared the code and it went away for 3 months till it came back yesterday evening.....gonna go get the codes pulled and start from their. SIGH getting annoyed, a little bit at a time

 

i may chalk this one up to lousy gas, mistakenly pumped 87 and since i have had premuim back init, its gone off....although once it did turn off for a day or so then came back on.

knock on wood it stays away. i was gonna fix it when i did my headers but now i dunno when i will do them

 

Scan the code Brian with ur scannet that u just bought

 

if u mean the one for the iphone, i haven't bought it yet....BTW john, NO CODES TO SCAN....doesn't show any history either.

 

i had the p0446 code before, i went to 2 shops they say my canister is out. they want me to change a new one($800). but i want to my mechanic he just changed the canister sensor ($60). then the code is off. it never come back.

 

im assuming your referring to the 02 sensor man? i know i need them....or atleast one of them i just have a long list before that

 

That is a good sign. That means that the computer already went through a driver cycle and didn't detect the problem that's why theres nothing in the pending codes. I would take a good guess that you probably forgot to tighten your gas cap. Using 87 instead of 91, from my highest opinion would not turn on the MIL. Our PCM are very sophisticated, it's smart enough to compensate for the loss in power and would adjust ignition timing accordingly and still maintain the car's efficiency. Yes, you will lose power but it won't misfire.
