Odd smoking problem? I have a 95 stock lt1 cc503 and no cats PCM4less tune
Ok I recently got the car out and noticed only at idle after warmed up lingering smoke out tailpipes but smells like unburned fuel. I thought maybe bad gas so I filled it up with fresh gas and went to work. I got done work and drove the car the same way home no smoke at all. Then got it out before work again and smoked like a chimney, literally so bad a passing car was honking at me to get my attention like I didnt know already. It's very embarrassing. I went to work got done and drove home no smoke. Seems to only smoke and cool mornings and doesn't over heat. I figured headgasket but how does it stop when it's hotter out? Runs great and idles normally when smoking. I have a wide band gauge showed between 14.7-14.9 when smoking. Anyone have any suggestions
