Your first step would be to confirm whether its really a vacuum leak before proceeding.. To do this Get an empty windex bottle and put soapy water in it and spray the vacuum hoses while it's running....If any r present, then bubbles will appear... Try it and let me know..

The high idle sounds more to me like a vacuum leak or at worst a manifold air pressure sensor gone bad.

Your overheating would then be due to the engine running lean (high amounts of air to a lower ratio of fuel), and a misfire reading on the OBD-2 system would confirm this. Have a trusted mechanic check the throttle body or air intake for a disconnected hose that leads to a small sensor located on the center of the bulkhead, behind the engine and directly over the transmission hump.

pls do rate the solution

thanks.

My check engine and check fuel cap light keep coming on after i changed the gas cap twice and reset the light it came back on what could this be. I drive a 06 lincoln navigator


You need to diagnose any codes you get
& smoke test the evap system, to find a
problem

Seldom does throwing on parts with a name similar
to a code work

Codes have nothing to do with installing parts

Clearing codes, clears all data needed to diagnose
the failed system & the evap system only runs every few
days,so you done as far as codes helping

Why would you replace a gas cap?
You were told, two EVAP Codes ,and what they were.
Have the vehicle smoke tested and repaired. You have two different size leaks,in that system.

Check engine light came on. Code P1456.


Did you change the gas cap with a Honda gas cap? Tighten it at least three clicks?
Also, Honda recommends that you never top off the tank when getting gas (only go to the click-off of the pump; otherwise you can get back flow into the system that will cause the code).
Tightening or replacing the cap will not immediately cause the light to go off; it can take up to three days of driving for the light to reset.
To check if your readiness codes (emission system) are set, turn the ignition to ON (II), without starting the engine. The Malfunction Indicator Lamp will come on for 20 seconds. If it then goes off, the readiness codes are set. If it blinks 5 times, the readiness codes are not set.
You can, of course, try resetting your engine light to see if it will come back on (which it probably will). I believe the procedure is:
Turn off the engine.
Press and hold the Select/Reset knob (odometer) in the instrument panel, then turn the ignition switch to ON (II).
Hold the knob for approximately ten seconds until the indicator resets.

Hope this helps you.

2006 Saturn Relay Check Engine Light


PO455 is a large evaporative fuel leak. A bad fuel cap is ONE of the things that COULD be the problem. Fuel system cleaning only lightened your wallet. Reading your post is confusing. Did all this start AFTER the Valvoline Wallet Flushing? If so , they left something loose or disconnected. I would find a qualified repair shop to fix the problem, and if it has anything to do with what Valvoline did, make them pay the bill.

P0442 check engine light code


The computer that read the code for you can also reset it.  If you don't have one, you can go to your local auto parts store and have them reset it for you.  This is what your code means P0442 Evaporative Emission Control System Leak Detected (small leak).  This is what Causes it and possible fixes: CausesA code P0442 most likely means one or more of the following has happened:
  • A loose or improperly affixed gas cap
  • A non-conforming gas cap (i.e. not factory/original brand)
  • A small leak/hole in a fuel vapor hose/tube
  • Other small leak in EVAP system
  • Faulty vent o-ring seal
Possible SolutionsWith a P0442, the most common repair is to:
  • Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
  • Otherwise, replace the gas cap, or
  • Inspect the EVAP system for cuts/holes in tubes/hoses

Gascap light comes on everytime i start up the car


I had this similar problem but gascap and engine light on. I changed out the gas cap cleared codes and both were back o. Went to the dealer he insisted it was the after market gascap changed in and cleared the codes. Before I even left the lot they were both back on. Finally they found the problem they had to change out some kind of pump and canister and it fixed the problem.

Check engine light on DTC P0456


P0456 is a code set when there is a very small leak (theres very small leak, small leak and a couple of others, your code indicates the smallest level of leaking). This can be caused by a vacuum line that is cracked or otherwise leaking on the evaporative (EVAP) system. It could even be from a gas cap that is not sealing properly, though typically a gas cap leak tends to set code P0441. Just the same, and since it is the cheaper way to go, start by replacing the gas cap and see if that clears the code and any check engine light you may have.

Once you replace the gas cap you may need to disconnect the battery for a couple minutes to reset everything if you dont have access to a scanner that can do it.
