I just fitted an A/R Ratio gauge and it's showed me something thats concerned me a bit..
On idle or if I'm driving then release the throttle completely it runs all the way towards Lean and then off the LED dial thingo.. Does it mean that it's running that lean??
Cos thats surely not a good thing right?
I just had a PFC fitted and tuned and when the car is hot it makes a funny noise out the exhaust on idle - it's not like a clean idle it sorted makes a popping sound or gargle.
