Car in question is a c5 4.2 v8. Tranny **** the bed back in November '12. Limp mode ever since. Warm weather has brought some overheating and some cracks in my reservoir leading to leaking. Well one of the cracks opened and dumped out all the coolant but I parked before hand. Then I patched up the holes and let it cool down for a ride home. About 10 mins. Temp was actually fine on the whole drive home too. Less leaking too. And now today I go to drive it and the whole engine is shaking like im out of gas and the ce light is flashing. Wtf is going on.
