Two thoughts come to mind one check you plugs thay can tell you a lot
Two after market sensors. I think its Tjkj that says all the time ( correct me if Im wrong ) dont use after market sensors use only OEM.
I think that is wishful thinking. Both sensors come with a lifetime warranty. Hard to think they are not made correctly. The thing hasn't idled right since I picked it up used with 74K on it. It is certainly running better now than it has since I got it.
I kinda screwed myself when I got it. It had been in a rear end collision and I didn't notice. The rear bumper is a different color and I came to find the fuel sending unit floating free in the tank. The leak detection pump had also been smashed from the tank being forced forward during the collision. All fixed now.
I will be checking other sensors and see how it goes. I cant remember the plugs I put in right off the top of my head. Got them from checker, recommended for the vehicle. Platinum something or other, paid about $4.00 a piece for them.
