Hello I am new I this forum and just wanted to ask for some help. Past two days my 2006 Honda Accord EXL has been acting weird. I was parked at a drive thru and the car shut off on me. When I was home sitting in the car it happened again in park. When I turn on the car it kinda shakes and same when I turn off the car. The RPMs are going between 1 and less like it wants to shut off. I have now noticed my car will stall out when I'm slowing down at a stop sign or traffic light. I've heard it could be the IAC valve, a EGR valve etc. I just need some help.
