When driving on highway the engine starts to run very rough and then the trac off light comes on and the car dies. I cost it to a stop and then all my gauge lights come on. Shut the car off wait a few minutes and try to restart. Turns over very roughly and then finally restarts after a few tries. I have replaced gas filter, coil packs, plugs, boots, igination timing switch, air filter, and cat converter. Also no codes have come up and have put it on a recorder chip. The engine seems to run fine but did notice that when it happens my igination timing goes from 15 to 4 then to 0.
Check the 02 sensor and the ignition switc.
