HI THIS CAR HAS A ROUGH IDLE!!!!WHEN I START THE CAR IT HAS A ALIGHT MISS . I TOOK THE THROTLE BODY LINKAGE COVER OFF SO I COULD PLAY WITH IT.I CAN HEAR A FLUTTERING OR TAPING SOUND THAT IS CONSISTANT . IM SURE ITS NOT A FOLLOWER!IT ONLY MAKES THE TAPPING SOUND DURING ACCELERATION. ONCE LET OF AND FUEL IS SHUT DOWN YOU CAN NO LONGER HEAR IT . THE CAR IDLES AROUIND 600 RPM. I JUST BOUGHT THIS CAR . I WANT TO FIX IT AND MY MANUEL IS NOT HERE YET . I HAVE HAD NO CHECK ENGINE LIGHT, JUST THE SERVICE LIGHT WAS ON!IT DID COME ON THOUGH AFTER I REMOVED THE INJECTOR COVER TO SEE IF I COUL FIND OUT WICH INJECTOR IT MIGHT BE.I PULLED A CONECTOR OFF ONE BY ONE. I COULDNT FIND THE ONE THAT WAS MISSING . IT DEAD MAKE ALL OF THE CYLINDERS MISS HARDER. AND IDLED WORSE WHEN PULLED OF. ( I NEED SOMEONE TO TELL ME HOW TO RETREEV CODES FROM THIS CAR . I KNOW WHERE TH BOX IS BUT HOW DO YOU USE IT?IM SURE IT IS AN INJECTOR BUT HOW DO I KNOW FOR SURE .I ALSO CHECKED FOR VACUME LEAKS. NOT REALLY HARD BUT I HAVNT FOUND ANY YET.IT STILL RUNS REALLY STRONG AND SMOOTH AND AT TIMES YOU CAN HARDLY FEEL THE MISS. IN OTHER WORDS IT DOES NOT MISS AT HIGHER RPMS LIKE A FOULED PLUG ONLY AT IDLE. I DID PUT NEW VOLVO PLUGS IN IT. I WOULD REALLY LIKE TO HAVE SOME INPUT ON THIS. I ALSO HAVENT CHEKED THE INTAKE GASKET TO SEE IF IT IS LEAKKING , BUT IF IT WAS WHY IS THE TAPPING SOUND THEREE. PLEASE HELP ME WES!!!!
