So my car check engine light has been on for a while, but it runs smoothly. This morning it was cold as, and the car started up roughly. Jolting etc, but only on idle. When I accelerated it ran smooth.
I took out all the ignition coils and checked each one, they look fine. The spark plugs are only 6 months old. But I noticed this pvc tube that had a shoddy repair done to it. It looked like it cracked and someone glued it, and now it has cracked again.
Any idea what the tube is called exactly? So I can order a replacement. http://imgur.com/a/HbUJ2bJ
