Need Help Solving a Idle Issue, Going Crazy
Alright so I am trying to solve a random bad idle issue. I've done research after research and can't seem to fix mine. Everyone else the steps work in the DIY guide but mine remains the same. I have a 2006 cobalt 2.2 with around maybe 184k. Just randomly at slowing down at stoplights/signs the idle will go extremely low and the car will shake and seem like it's going to stall. I've cleaned the mass air flow sensor many times, I've changed the fuel filter maybe 15k ago(still did it then too) I've replaced the plugs with stock ac delco gapped correctly, replaced the coil on plugs, air filter, cleaned the throttle body and its shiny as ever. But the TB seems like it has scratches on the surface when I cleaned it for The first time. I have 0 codes besides a only sometimes large Evap leak that I also can't solve after many gas caps (ac delco). It could go days without doing the horrid idle or it could do it every time I stop. Please help! I'm stumped
ADDON: I also just thought after I posted that to add also that I have a completely random no start. First crank just cranks and won't start and second crank starts right up but with that low shaking idle issue
