AFR question.
The reason I ask: My LC-1 shows I drive around and idle between 18:1 and 21:1 most of the time. At WOT, the gauge shows me coming down into the 13:1 range. I know my tune is wack, but surely my gauge cannot be accurate when reading these higher numbers...? (I'm running open loop maf btw)
AFR that lean will give you all kinds of problems.
Is the sensor installed after the CATS?
Do you have a lot of surging and KR?
