Hey guys so my buddies car is running rough it sounds like its misfiring I hooked up my scan thing through my laptop and check misfires and it wasn't reading any... I erased the old codes thinking they had something to do with it and the only thing that came back was a pending p0010... He has a 09 lt I belive is the model I think it has a 2.2...... So he is what's goin through my head he hasn't changed the plugs for about 3 yrs so they need replacing I'm gonna pull em tommorow and see how they look... Also I heard the lap engines are known for dirty oil and messing with the camshaft sensors so where goin to runner a cleaner through it then change the oil... He says it only runs like crap sometimes like its a hit and miss same with the code comming and disappearing... So what r ur guys thoughts?
