Hey guys ! Been having some strange behavior when start the LR4 for over a week. When truck has been sitting for an hour or more ( engine cold ), the RPM will go up to 4500x for the warm up instead of sitting in the 1500x range as it should.
This is probably very bad for the engine as it revs very fast right on start. After the warm up, rpm goes back to normal and truck runs relatively fine but I noticed it stutters a bit and idle varies in the 1000s.
ObdII gives me the following errors on both banks. I resetted the error codes and they came back right away.
My local mechanic tells me he cant do anything since its most likely an electronic or software issue. He tells me something is wrong with the cylinder firing as well and this is probably the cause of the stutters so I might have 2 issues.
The truck is 2014 and has over 200 000kms. Closest dealer is 10 hours away. Truck runs fine once hot and if I stop engine and start again right away, it does not do the high rpm startup thing.
I am scared of using it and damage the engine but I need to get it back on the road asap as it is my main vehicle.
See obdII diag codes below. Any tips or insight is appreciated.
Thank you !
