I have a very strange intermittent problem that just started happening about 4 weeks ago. After about five minutes of driving when I come to a stop the car idles pretty low and vibrates, it never stalls. After about 30 seconds of low idle (half way between 1 and 0) the car recovers and idles normally. From that point on, say I'm in stop and go traffic the car idles low at almost every stop. It will then usual stop the low idle once I've driven the car some distance and gotten the rpms up, but only after it goes through the session of low idles.
It's so strange and I originally thought it was just a bad tank of gas, but it does it on almost all the different brands of gas (Exxon, Amaco, Mobil, Citgo). I don't even know where to start looking and I was hoping someone here could help me out, thanks.
Thanks in advance
