Back to back posts oh well I have a question about my engine being cold real cold and running rough till it warms up. Then went I get to where I am going for over a few hours it gets really cold again? Ya my ride is sputtering till it warms up and then it like sounds like an exhaust leak or something? Could be that thermostat or maybe oxygen sensor or what. I have put a little change in my ride and I love to take care of it for sure When it warms up it runs soooo good it's really strange. I bought my Jimmy and a Chevy Blazer out in IL. the Blazers engine was burnt to crisp in the Blazer, so I parted it out got the transmission out the starter the front window the back window with defogger the interior panels the console inside on the ceiling I even took the ceiling board out and swapped it out too.Did. Did the ball joints front shocks brakes and rotors a few times it has been over a couple of years now and I am still loving my ride. So if there are any ideas or similar situations I would soo much appreciate your comments, check out my pictures I've had some good times traveling across the US and back a few times and the ride really means something to me if ya know what I mean.
Again Thanks.
