Help with my co/hc please
My 3.3 turbo can't seem to run unless very rich. The minute I start to lean out the motor it revs up and down. Is there an initail starting point for adjustment ? My sidedraft m.g's would start with ten turns rich from full lean and then you would start fine tuning, anything similar for these motors ?

oscillating idle -> vacuum leak or bad recirculating valve gaskets

Oscillating idle on NA cars usually means a too rich mixture. Is it the opposite for turbos?!

mine settled after tightening hoses and replacing recirculating valve gaskets.
