There's always the old carb cleaner trick. Spray some carb cleaner around where you think the leak is and if there is a leak it'll suck the carb cleaner in and rev up a little.

the car idles fine!, but if it gets to tempature and then not run for 20 min then driven again, this problem is there, right when that meter went to 20 the surgeing started, what could cause the +20?

so an exhaust leak could cause the ltft b2 to jump so high?, this means that bank 2 is running extremely lean right?, wich if its an exhaust leak the right side o2 is right after the flange, am I getting anywhere?

You could also have a fouled O2 sensor. I had a bad driver's side one and my fuel trim would fluctuate from normal to +30 speradically.

Check out your plugs and see what condition they are in.

What have you done to the motor recently? If it was a small intake leak I would think the B2 LTFT would drop (less positive) as you increased the load. It stays nearly the same?

a while ago changed cam, chain, pushrods, valve springs, headers, spark plugs, all the gaskets and seals were new, the only one I skiped on wuz the valve cover gaskets cause the old ones looked perfect! a few weeks back right after I filled up with gas, the ses light came on and wuz sputtering, I thought it wuz bad gas, so drained the system, put new filter and put fresh gas and seemed ok,
