930 with Motronics running alittle funny

Hello all I have a 1988 930 running Motronic, It was original built by Prototech. Its been running great for years. Recently I did a track day, ran fine all day except it was running a little hot so i wasn't pushing it. Since then about 2 months the car sat in the garage. Well took the car out the other day and noticed that if the rpms are @ 2000 to 3000 and running steady it starts to jerk, if I hammer it or just give it gas it goes just fine. I did a basic tune up Cap, Rotor, Plugs & Air Filter, Didn't seem to help. Awhile back I had a head temp sensor go bad, which made it run rich. It actually barley ran, was super rich. This is not that bad but may be a sensor is bad? Any thoughts would been really helpful. Thanks
88 911 Turbo
