To JOE. Hey Joe its DAN again. I have a 2005 Chevy Colbolt 2 door coupe 2.2L Automatic.
I want to thank you for you spot on answers about when my check engine light came on with the Codes ( PO 171 and PO 455 ).
I wrote down everything you replied your answers to my questions step by step for my mechanic.
I will be bringing him my car on MONDAY 1/12/15 to fix those issues with my car.
Now I have a couple of more Questions for you JOE.
TODAY ON SATURDAY 1/10/15 I started my car for the first time this morning and I let it warm up for 15 minutes.
Megan I started my car the ( CHECK ENGINE LIGHT WAS STILL ON ) obviously because I haven't yet had those problems fixed yet. However I went to mcdonalds today after I started my car for the first time today. After I was done at McDonald's, my ( CHECK ENGINE LIGHT WENT OFF ).
So I found that to be strange, I thought maybe the ( CODE PO 171 system to lean bank one cleared its self up on its own ). However when I got home, I took my OB2 SCANNER AGAIN AND SCANNED MY CAR AGAIN.
THE SAME CODES ( PO 171 and PO 455 ) still were showing on my OB2 SCANNER EVEN WITH THE CHECK ENGINE LIGHT OFF. So I definitely know that there are those problems that you said there were according to the codes I told you. I will get them fixed on MONDAY 1/12/15.
QUESTION 1--- ( ON MY OB2 SCANNER FOR CODE PO 455 THE EVAPERATIVE SYSTEM I WENT TO THE OPTION WHERE IT SAID ( DIAGNOSIS OF ACTUAL PROBLEM ACCORDING TO TGE CODE IN MORE DETAILED FORMATE.
IT SAID ( EVAP ( VP ) ( H20 ). THEN IT FLUCUATED BETWEEN TWO SPECIFIC NUMBERS.
THE NUMBERS WERE ( 6.082-6.087 ) and they were going back and forth back and forth back and forth.
NOW I ALREADY KNOW WHAT THE CODE DIAGNOSIS IS ACCORDING TO YOUR ANSWER FROM MY PREVIOUS QUESTION BUT LIKE I SAID I WENT A LITTLE MORE IN DEPTH.
SO WHAT DOES ( EVAP ( VP ) ( H20 ) MEAN?
AND WHAT DO THE TWO NUMBERS THAT KEPT ON FLUCUATING BACK AND FORTH MEAN? THE NUMBERS AGAIN ARE ( 6.082- 6.087 ) THOSE TWO SPECFIC NUMBERS KEPT GOING BACK AND FORTH ON THE ( OB2 ) SCANNER WHAT ARE THOSE TWO NUMBERS?
ARE THOSE TWO NUMBERS INPORTANT?
WHAT IS NORMAL AND NOT NORMAL ABOUT THOSE NUMBERS?
ALSO WHAT DOES ( VP ) MEAN AND ( H20 ) MEAN?
QUESTION 2 WHAT DOES THE ( EVAP PURGE MEAN )?
THERE WAS ONE SPECIFIC NUMBER SHOWING ON MY OB2 SCANNER AND THE NUMBER WAS ( 12.9 ).
WHAT DOES THAT NUMBER MEAN?
IS THAT NUMBER NORMAL OR NOT NORMAL?
QUESTION 3---- GOING MORE IN DEPTH AGAIN WITH MY OB2 SCANNER IT SAID ( FUEL SYSTEM 1 -- CLOSED ) ( FUEL SYSTEM 2 NOT APPLICABLE )
WHAT DOES IT MEAN FUEL SYSTEM 1 CLOSED?
ITS THAT NORMAL? OR IS THATCA VERY SERIOS PROBLEM?
NOW IT SAID FUEL SYSTEM 2 N/A NOT APPLIABLE I AM ASSUMING THAT STANDS FOR?
Now when I drive my car everything seems to be running fine and smooth while driving.
Everything also seems to be normal while sitting at a traffic light fully stopped also while ideling.
Nothing seems out of the ordinary, but I know that my mechanic needs to do what you said he needs to check with the CODES.
HOWEVER I DID NOTICE WHEN THE CAR IS IDLING WHILE IN ( PARK ) WHEN THE CAR IS ON THE THE ENGINE IS VERY BOUNCY AND IT'S JUMPING AROUND A LOT WHILE THE CAR IS ON AND IN ( PARK MODE ).
DOES THAT HAVE TO DO WITH THE CODE ( PO 455 ) EVAPARATIVE SYSTEM ( VACCUM LEAK AND A HOSE LEAK )?
AND OR DOES IT HAVE TO DO WITH THE FUEL PRESSURE SINCE I PUT THE INJECTOR CLEANER IN WITH HARDLY ANY GAS IN THE CAR POSSIBLY CAUSING THE FUEL PUMP TO BE DANAGED OR THE FUEL FILTER BEING CLOGGED?
BUT HOW COME THAT ONLY IS HAPPENING WHEN THE CAR IS IN ( PARK MODE WHILE THE CAR IS ON ) AND EVERYTHING ELSE WHEN DRIVING AND SITTING AT A TRAFFIC LIGHT IT DOESNT DO THAT THEN?
BECAUSE WHEN I DRIVE AND WHEN I AM SITTING AT A TRAFFIC LIGHT EVERYTHING FEELS AND SEEMS TO BE NORMAL, NO HESITATION, NO STUTTERING NOTHING LIKE THAT HAPPENS WHEN I AM DRIVING AND WHEN THE CAR IS IN ( DRIVE MODE WHILE IDLING ITS RUNNING SMOOTH?
ALSO WHEN I TURN MY HEAT ON, THERE IS A WEIRD NOISE COMING FROM UNDERNEITH THE GLOVE CONPARTMENT, I CANT EXACTKY DESCRIBE THE NOISE, ITS SOUNDS LIKE A WISSING NOISE WHEN I TURN MY HEAT ON AND THE NOISE IS COMING DIRECTLY UNDERNEITH THE PASSANGER SIDE GLOVE BOX COMPARTMENT.
WHATS THAT NOISE COMING FROM?
PLEASE CONTACT ME BACK AS SOON AS POSSIBLE WITH YOUR EXPERT ANSWERS AND EXPERT ADVISE AND EXPERT ANSWERS TO ALL MY QUESTIONS I PROVIDED TO YOU PLEASE.
PLEASE CONTACT ME BACK AS SOON AS POSSIBLE.
AGAIN THANK YOU VERY VERY MUCH,
have the same problem?
