hey thanks for replying, um the plugs and cap and rotor are about a year old and the car runs fine once its started. Its more about time theen it is about temperature like one time it was pretty hot out, the car sat for 8 hours and it gave me the same problem, it trys real hard to start, like sputters it just wont catch. Im not that fimiliar with testing all the sensors, can it be done with a regular multitester, what would you suggest i should check first
