Legend L 88, 123k miles, automatic

Have gotten following codes in last six months.
Code 8(TDC sensor), happened once about 6 months ago. Dealer checked (costed 45 bucks)and found nothing wrong. Was told to replace distributor (quoted over $400) if the same code comes back. However, never got the same code again.

3 months ago, got code 12 (EGR system). Reset ECU and the code disappeared.

2 months ago, got code 7 (Throttle angle sesor), could not get rid of this code by resetting ECU. Check engine light usually comes on after 10 minutes from starting cold. No notice on difference of car performance. Dealer told that sensor is also within the distributor body.

Question to all: is it still safe to driving by ignoring the light and code? Living on tight budget.

Ignoring the fact that the problem may be serious and lead to further damage or being stranded, as I understand it, the engine runs in a safety mode when there is a code in the ECU - doesn't matter if the light is on the dash - look at the ECU for a flashing code. The safety mode runs richer leading to lower fuel economy (maybe 2-3 mpg) and leads to wear on your catalytic converter.

IMO, the codes should not be ignored - owning a car with high miles leads to expensive repairs sometimes. Do the work yourself and save some $$ - just use quality parts.

In general, most cars that are computer controlled have a "limp-home" mode. When fault codes are triggered and stored, the ECU reverts to this limp-home mode; the engine is controlled by a pre-determined set of parameters instead of relying on sensor feedback (some ECU's may look at a limited number of sensor feedback loops).

You can drive the car with the check engine light on. But I wouldn't do it for an extended length of time.

From your post, I would definitely look for another dealer or mechanic. The throttle angle sensor isn't in the distributor. It's located at the throttle body.
