Any ideas? I have an O2 simulator for the downstream, and it's never caused any problems yet...should I suspect this one?

Re: Just following the trend...BLLdogg

figure out why you are going lean. do you have a vacuum leak? is the fuel pressure strong and steady? evap leak?

Re: Just following the trend...BLLdogg

I seriously have been really busy, and the weather has been non-stop raining. But when I start my car ( keepin' the oil fresh through the motor!! ) I notice at first, it idles smoothly, but after it runs off choke(I think it does at least), it seems to start missfiring then...helpful info? I noticed after I shut it off after she miss fires, and start her right back up, she miss fires a little worse.
