So I was driving home from work the other day when my mkiv stalled at a traffic light (its an auto) and after I restarted it the idle was very rough. After getting home I restarted the car again and it seemed to run fine at a normal idle so I was confused. I restarted it once again and it was yet again alright. A few hours later when I started it again, it idled above 2000 rpm so I disconnected the battery and let it sit over night. This morning I tried to start the car again and it would only start for a second then die. If I peddled the throttle it would stay alive though.
I just changed my IAC valve a couple weeks ago because I was having symptoms similar to these but after I replaced it all problems disappeared for a few weeks. I was thinking my tps or crank position sensor could have just gone out as well or the IAC valve I got could've been defective?
I tried plugging in my OBDI code reader but it couldn't connect
Thanks for your help ahead of time people! Much appreciated.
