Hello! This is my first post to this forum. Thanks to Wpgshark for pointing me to it.

Recently, my "OB" 928 started to have a hesitation when accelerating. At times it was a second or two before acceleration would kick it but then would run fine. Even more recently, it has begun to simply die out when the gas is pressed. I was hoping someone might have a few suggestions for a new 928 owner. As I mentioned in the title, it is a 1979 automatic.

thanks!
Nathan

your going to need to check the control and operating pressures to figure out the issue ,
Roger has a set of Gauges.

But off the bat I will say you probably have a vacuum leak,
once the pedal is pushed the system goes to a leaner mixture then it stalls.
If a vacuum leak is not found the gauges are needed

Thanks for your reply!

Because of your message, I did a search for "vacuum leak" and found a great article on Rennlist about possible reasons for hesitations: https://rennlist.com/how-tos/a/porsc...itating-378349

Very helpful.
