Maintenance & Repairs: 911 vs. 993

[Brian Minkin]

The primary difference in a 993 is not simple routine maintenance but that it is an ODB2 Diagnostics car and check engine light coming on and needing diagnosis and subsequent repairs to shut it off are not as simple to address as repairs to a 3.2 litre engine as found in your car.  These cars all seem to develope a problem that throws the check engine light especially if they are driven in city traffic rather then wide open.  It invloves a passage in the heads that clogs up and ultimatley can require a top end rebuild on a car with as little as 70K. Still very similar to a 3.2 car to service and do routine maintenance on.  However the injection and emmisions system are more complicated.
