    If you had an intake gasket leak, you should've seen lean conditions under boost, unless the car was tuned with this issue. The O2 sensors on these cars cannot compensate for vacuum/intake leaks. It's good to hear you found something though!

    But like others have mentioned, pulley down and run a safer pump gas tune or things will become worse.

    Maybe you can find a member close by.

    I had went and looked a a cobra here in San Antonio. Guy having issues running. I only scanned it. But listening to it running I think he was down a cylinder.

    These to me are common for head issues

    I had valve issue at 60k/120k/200k

    At 420k now.

    A basic compression test you should be able to do. Or get done.

    I do this every time I have a problem 1st


    There have been some recent threads on engine miss that ended up valve issue after they threw parts at it.

    We all read the same shop manual but forget

    Always check all the basics first
    Was told you need fast. To run

    Fuel
    Air
    Spark
    Timing

    Fast

    Base engine is always skipped. Compression test

    Did your mobile mechanic check fuel flow?

    So when I goggled intake leak testing and symptoms and the mechanic did spray starting fluid and it did react the way it says when you have an intake leak. Am I missing something?
    I dont know what caused the intake gasket to start leaking but I think it has for a long time and it has gotten so bad that now the car will hardly run.
    I just wish I had the knowledge to take it apart but I dont.
    Thank you

    I’m pretty sure pcm would pick up leak as po171/174

    Just the slightest leak on pcv line

    The intake gasket is a re use gasket but age may play factor

    No sealants are used and it’s not cranked down like old engines

    Many threads on snapped bolts. These are just past hand tight with 1/4 in tools Bolts are tiny.

    Did he check them?

    Also if you don’t do your own work

    I suggest you ask for old parts after jobs.

    To many crooks out there.

    The fuel filter if you haven’t replaced again do have done.

    They put this thing in the hardest spot to change. I can see a shop saying they did and not really did

    No I haven't checked the bolts and neither did the mechanic.
    And used to get those codes alot and I would just change the O2 sensors.
    I will check the bolts for tightness.
    Thanks

    Those codes weren’t for bad o2.

    It was o2 telling you that you have air coming in engine that’s unmetered

    The pvc line. On stock intake goes under the intake.
    Intake must be pulled to fix this hose

    It’s a common problem from oil.

    The hose will harden.
    It is just pushed on a barbed fitting without a clamp

    This hose will not pull off but it will spin which is a vacuum leak.

    This nipple is also just below where the mechanic sprayed

    And with type of intake gasket it will pass under and around ports to under intake.

    There is a link with pic.
    Google

    03 cobra vacuum hoses documented

    Will be a pdf link

    Some do plug this line

    Can’t say for you.

    Did he do a vacuum test?

    Pcv line elbows are so common to bust a hole
    They also crumble and soften from oil

    Terminator FAQs


    If you haven’t read thru these. It has everything.

    Once these get modded. Almost anything can be causing your issues

    Knowing more about what your car has may help guide toward trouble areas with mods

    Drive ability is why I stayed as close to stock as I can.

    It’s more old school tool. But very valuable if used right.

    Fuel testing is old school carburetor days
