So I have a 03 1.8t sedan and when I let the car run in park or I’m sitting at a light (sometimes but getting more often) the check engine light starts to blink and the car starts to do like a little rumble/shake and it starts to rough idling and I have ran the codes multiple times and it says my idle control module rpm module or something like that along the lines can’t remember at the moment and misfires in cylinders 1, 2, 3 and sometimes 4 I have had the car in the shop and had a lot done and a lot not done that should have been done. All I have done is a touchscreen radio some after market speakers that the passenger side door won’t work now for some reason but that’s for a different day and time. But I really need help because I’m at a loss and I love this car so much and it’s been me and my wife’s car I’m just at a loss! I’ve looked and looked and looked for answers and something to maybe help or even some where to start because like I said I’m lost!!
