Could running with these codes harm my engine??? I got a Service Engine Soon light with the following codes this week:
* P0135 - O2 Sensor heater circuit malfunction, Bank 1, Sensor 1
* P0135 - O2 Sensor heater circuit malfunction, Bank 2, Sensor 1
* P0300 – Random/multiple cylinder misfire
Because tomorrow is the last bracket race of the season at our local track I don’t want to miss it. However, is there any chance I could damage the motor if I ignore the codes???

the p0300 isnt good. if you can swap o2's then id recommend that. If it were just the o2's, id say go for it, but the misfires isnt something you'd wanna be running the car hard on.
