I GOTTA VACUMM LEAK SUMWHERE UNDER THE HOOD. IT IDELS HIGH SUMTIMES AND THEN SUMTIMES IDELS JUST RIGHT. BUT THEN AT OTHER TIMES IT WANTS 2 STALL. WHATS AN EASY WAY 2 FIND THE LEAK? P.S THIS CAR HAS HAD MULTI MECHANICS WORKING ON IT SO WIRES AND HOSES ARE BLOCKED OR UNHOOKED. BUT CAR RUNS GREAT. NOW ON 2 THE CLUTCH. I MESSED UP MY STOCK CLUTCH RACEING AND IM LOOKING 2 GET ANOTHER HP CLUTCH. WHICH DO U THINK IS BEST?
