My bud has got a 07 classic lbz 4" exhaust and a evo but its set to stock recently the truck started ticking at idle and the ticking speeds up as the rpms go up but goes away after bout 1500 rpm. The truck also goes into limp mode very easy even with the evo set to stock setting a p0087, sometimes after idling a while in the heat it will be in limp mode when you try to drive off. To top it off it smokes like it has a decent sized tune loaded. Any ideas? New fuel filter and new air filter. Thanks James
