i've noticed this on my 00 gt the past two times i have driven it. it only seems to do it on a cold start. the car starts up and idles very rough. a good puff of blue smoke as well. the erratic idle lasts maybe 2-3 min then clears up and the car runs fine. the smoking only lasts 20-30 seconds on initial startup. smells of oil. the two mornings it has done this has been pretty cold. the car is not a DD. on average it gets driven once a week.
the 'service engine soon' light has been on prior to this. there are 3 codes -
p055: evap leak/gross leak/no flow
p0153: oxygen circut slow response bank 2/sensor 1
p0442: evap small leak
fuel pump was replaced a while back and some time passed after replacing it, the light tripped. then, it was just the evap codes. i assume we binded up gasket maybe around the filler neck or the gasket on top of the tank during the install. but could a failing O2 sensor cause the rough idle and blue smoke? after the initial startup, the car runs perfect and no smoke whatsoever.
thanks in advance for any advice.
