My L keeps giving me a Check Engine light after driving some distance then coming to a stop in gear. I check the code and it is: Bank 1 and 2 are lean. Does anyone know what I should look for? Also the idle is 589rpms when this happens, is that right?

 

Pull the chip and see if it happens. Your new headwork may be leaning it out. Check your A/F's.

 

Your low idle rpms may be due to those ice-house, cold plugs you're using---btw, I'm using them too. Mine misfire, especially noticeable at low rpm driving and at idle.

The lean codes........clogged fuel filter?.........hose blown off one of the internal fuel pumps?

Changed my sig. to show current mods. I do not have the misfire with the Denso's but did with the BR7EFs.
