Hello, I'm new here. I live in Pennsylvania. I own a 1994 SL2 with 124,000 miles which I'm not driving currently. (It has developed a tapping in the engine, I believe it either needs a new head or a new timing kit but I'm not sure) I recently bought a 1999 SC2 with 101,000 miles. Runs really good, except it seems to be burning gas pretty quickly. I did some research on here already and I determined it may need a new thermostat and engine coolant temp sensor so that my engine isn't running so cool and using more gas. (correct me if that is incorrect) It also starting throwing the po410 code for the secondary air injection. I have another thread already open on that subject.
