dryheat Posted February 4, 2011 Report Share Posted February 4, 2011 Need some help guys. I believe my stock L20b with a Weber 32/36 DGV is running too lean and this has been the root cause of my elevated cruising temperatures. I installed a AEM wide band O2 a while back and at idle it hovers around 12 ish. If I'm just crusing down the freeway it seems to be 14.5 +- . Any acceleration or increase of load (a hill) to the engine causes the A/F mixture to go off scale lean. It runs fairly well but I'm concerned about the effect of running too lean for too long. Plugs are whitish ... kinda/sorta spotty light tan if you look at them in just the right light. Here are the jets as installed - Primary Main 140 Air Corrector 135 Idle 55 Secondary Main 165 Air Corrector 160 Idle 50 Timing 12 degrees with 35 degrees of advance at 3000rpm Any help would be greatly appreciated.
