I think you should start with the cheap/easy first, and work up from there.
That being said, it took me about two weeks to properly burp mine after the return hose broke...and a week to do it after the throttle body heater was replaced. Good times.
I kept a set of tools with me (always do) and whenever it started to heat up I would shut it off, fill up the bottle if low, and open up the top hose and fill it up and clamp it back down. Be careful when opening up the bottle and the hose of course. Then I'd let it run for a few minutes to see if it would spike back up, and it usually wouldn't do it again for a few days. Now...all is well, but the leaking o-rings. Time for some more Bar's leak stop. :dance: See if I can get another two years without tearing apart the dash for that job.
