I cannot for the life of me figure out what this sound is and what’s wrong with my car. No codes, MAF readings are normal, all fuel trims read normal, no vacuum leaks I can find. It was doing this a few months ago, I replaced the coil packs and spark plugs and that fixed it, now it’s back. It’s jerky when you accelerate lightly and clears up a bit when you romp it, but is still slightly noticeable. thinking of taking the coil packs and spark plugs back out to check for water or oil and if there is replacing the valve cover gasket. Any suggestions??
