Ok well i've been having problems since i bought the car a couple months ago. The car has all new oxygen sensors, new plugs, new MAF. I have been getting cyclinder misfire codes on 1,2,3. I recently installed a GIAC chip. Yesterday my water temperature guage quit working so today i changed out the CTS. Temperature guage still is not working. Still getting heat though so I know car is still fine. I did a misfire count and cylinder #2 is misfiring about once every 2 seconds. I am also getting codes P1176,P1177, and P1250. Anyone help me out? Thanks
