Hi all I’m trying to investigate a very slight rough idle and low rev issues (barely noticeable) and the first thing I checked was the codes I have one for the coolant temp sensor but on the cluster it’s reporting back ok so would this be a problem? How hot should it report back after a mixed driving session the hottest I get is 80c?

im 99% sure my issue isn’t fuel system related as I run a fuel fuel setup I have ran for 8 years no issues and it’s the same on both.I’ve also changed all coils and plugs and cleaned the mafs as they were pretty clean anyway.


Any ideas

If nobody knows could someone with everything running right turn their secret menu on to coolant and tell me how it looks over an average drive? Cheers
