I have an aftermarket stereo installed and my car starts hard after whenever I have my stereo turned on at any volume, but the car starts fine after about a day or two with the stereo off. The hard start is worse at night with the lights on and all, but the voltage is never below 13.3v. My car works perfectly before I put the stereo in so in some way my car don't like the additional electrical components. My stereo is capable of pulling more than 120 amps but my car still starts hard even if the radio is on low volume. This is really confusing me...:hmm:
btw when the car threw a misfire it stored a misfire code, PO606 and P106. But guess what? The check engine light turned off by itself when I had it parked for two days and runs fine. Then I turned on the stereo for a road trip...starts hard after that.:annoyed:
