Is that normal? If not, what could cause it? Thank you. Car pops and sputters when put in drive and quits. The same when start up. Seems to run fine at a fast idle.

At least one of the cylinder is misfiring and whern this occurs, the catalytic converter would get red hot. That explains the popping and sputtering.
