Well,the temp sensor with one wire which is in the front right side of the engine is just for the gauge,it has nothing to do with the ECU,so it won't affect the engine running.What fuel pump are you running?What's the fuel pressure you have set up the fuel pressure regulator?What colour are the injectors?What boost are you running it?Is it chipped?If you can gimme some info and I will try to help you out I really like the look of your car,I wish mine had 3 doors too
