I started my 514 and moved it out of the garage but only let it run for about 1 min. When I did a re-start it blew smoke from the passenger side pipe...just a puff and it was gone...
I let it warm up...took it for a ride and it ran great...
What is this all about?
The next problem ,and it might be connected is that I have a small backfire on occasion when stoped at idol (at light or stop sign) also on the passenger pipe...
Are either of these problems a real concern...as I said the car seems to be running great
Thanks
