So I have this huge problem that has been affecting my car for a while. To start off the codes popping up are all four 02 sensors heaters, but I ran a diagnosis and they work perfectly fine and the code for an eval purge valve comes up too. Also if I'm doing a pull my engine starts to misfire and it usually breaks a coil pack with it. I've purchased four coil packs in the last month. Any tips?

Hello,

I have seen this problem before the PCM is bad. Here is the location under the hood so you can replace it with a used/rebuilt unit. Check out the diagrams (below). Please let us know what happens.
