I'M NOT SKILLED IN THE SENSORS AND STUFF ON THESE NEWER RIGS. YET
BUT AS FAR AS SEARCHING FOR VACUUM LEAKS---SEARCHING FOR THEM HAS BEEN AROUND EVER SINCE THE AUTOMOBILE WAS INVENTED
SOAPY WATER IS A. NO-GO!
VACUUM DOES NOT "BLOW BOBBLES". IT "S. UCKS"! (BUBBLES WOULD BE INSIDE)
IT S. UCKS THRU THE LINES TO "OPERATE" COMPONENTS
YOUR PCV CONSTANTLY S. UCKS----WHERE DOES THE AIR GO?
THRU THE INTAKE AND INTO THE CYLINDERS (THE PISTON DOWN ACTION "MAKES" THE VACUUM. IN SIMPLE TERMS)
SO. IF YOU HAVE A "VACUUM LEAK"----UNWANTED AIR GETS IN, AND SORTA THROWS OFF THE AIR/ FUEL MIX IN WHICH THE ENGINEERS TRY TO MAKE AS NEAR PERFECT AS POSSIBLE. THIS "WRONG MIX" IS POSSIBLY YOUR PROBLEM. IF YOU HAVE A VACUUM LEAK
YOU MUST FIND THE LEAK--IF ONE IS THERE
HERE'S THE METHODS I KNOW:
1) LOOK! LOOK FOR IT WITH A STRONG FLASHLIGHT--LOOSE HOSE--BROKEN PLASTIC TUBING--SPLIT HOSES---LOOSE FITTING HOSES
2) TUG AND TOUCH HOSES AND PLASTIC TUBING--IT MAY LOOK FINE, TILL YOU "OPEN UP" A CRACK
3) LISTEN FOR A S. UCKING SOUND.I HAVE USED THIS MANY TIMES, A 3-4 FOOT SECTION OF HEATER HOSE/GARDEN HOSE, ONE END IN MY EAR, THE OTHER END USED LIKE A STETHOSCOPE
4) YOU CAN SPARINGLY SPRAY CARB CLEANER, STARTER FLUID, ETC, ON STUFF TO INCLUDE THE INTAKE. WHEN THIS GETS S. UCKED INTO A "LEAK"----THE ENGINE RPM WILL GO UP--OR SORTA REV FOR A SECOND OR TWO. THE ENGINE IS GETTING "EXTRA FUEL" NOW--NOT THE UNWANTED AIR. SHOULD THIS "REV" OCCUR, YOU ARE PROBABLY REALLY IN THE BALLPARK OF FINDING THE LEAK
5) I ALSO TURN ON MY PROPANE TORCH (BUT NOT LIGHT IT) I SORTA WAVE THE PROPANE IN THE SUSPECT AREAS----LISTENING FOR A "REV" AS I GO
XXX) USING METHODS "4" AND "5" IT IS BEST TO DO THIS OUTSIDE-AWAY FROM OTHER CARS--AWAY FROM FLAMMABLE STUFF!
"4" IS MORE LIKELY TO BE MORE FLAMMABLE, AS YOU ARE SQUIRTING A "FLUID" THAT COULD STICK TO STUFF AND BURN IF IT WERE IGNITED
"5" MAY ACTUALLY "LIGHT THE TORCH", IF THE GAS WERE IGNITED, BUT THE GAS DISSIPATES QUICKLY AND USUALLY DOES NOT SET STUFF ABLAZE ON THE ENGINE, LIKE A FLUID
ANYTIME YOU ARE DEALING WITH A RUNNING ENGINE---OR INTRODUCING "FLAMMABLES" ON OR NEAR IT. YOU REALLY NEED A "BLANKET" TO SMOTHER ANY SMALL "FLARE-UP" AND A OPERATIONAL FIRE EXTINGUISHER IF THE BLANKET AIN'T CUTTING IT!
BE SAFE--USE COMMON SENSE!
OK I'LL LET YA'LL CONTINUE WITH YOU SEARCH TO FIX THIS THING
