1990 964 Rough Idle


Vehicle Information: Model: C2; Year: 1990; Body Type: Targa; Total Mileage: 76000;

Recently had major tune up. Afterwards noticed engine idle RPM/oil pressure was not steady. Idle is slightly lower than normal and will occasionally stall. Engine stalls/recovers at various street driving speeds. Also tach will drop to zero and engine continues to run. Any ideas? Any recommended shops in my area of NC?
