Is the coolant system properly bled and topped off??? This is helpfull to know before shotgunning an ECT sensor, especially if accessibility is difficult.... -- Mike 93 Cobra |

It would be nice if I could read the codes in the check engine like I used to in my dodge daytona, rather than having to connect the code reader every time. |

I replaced both sensors and so far the car has ran better than before with no error codes, the only thing is that the idle gets rough from time to time, it is not a 24/7 thing, does anybody have an idea what it could be? Thanks a bunch for your help! |
