2007, Mitsu Endeavor LS, 6cyl3.8, 52K Catalytic Prob Sign In

Am I getting hosed by Dealership? Took to local respected shop for tune-up and check Service Engine light. Car running a little rough and slightly missing at start-up ONLY. They state car does not need tune-up till 100K and Catalytic needs replacing but can get replaced by Dealer under 80K Warranty. I trust them as they could have taken the repair and hit me for a $1,000 for Cat Replacement. So I took to Dealership (it is a new Mitsu Dealership, small grimy place, not professional at all...kids waited on me, and they had no record of my frikn appt...not a great first time visit!), they say needs plugs and wires and have to drop the manifold to install. A cylinder is not firing well and causing leakage into Catalytic. Wants $500 for tune-up BEFORE replacing Catalytic. I don't trust the Dealer. Expert advise anyone? Thank you

OK, so how many miles on the car?

If the plugs are the cause of the catalyst going bad, then you should have them replaced. Misfiring will take out a catalyst, which it may have in your case.

Book time on spark plugs is 2.2 hrs
Maybe 1 hour for diagnosis?
Spark plugs are around $90 for 6 for the correct OEM plugs after mark up.
There are no spark plug wires, but it does have boots. If there is bad coils, those could be around $50 a piece.

I don't think $500 is far fetched if your getting this done by the dealer.

You really need to figure out why it is running rough and missing when you first start it before going after the catalyst. Cure that first. It may have nothing to do with the ignition system.

HT - Says 52,000 in subject line. OP (that's original poster) are you the original owner and miles is true? I default to what your owner's manual says for service intervals.


I take it the light that is on is either the warning light or a reminder light so help me/us help you. If that's a SEL (Malfunction Indicator Light) and you said it doesn't run exactly right so think it is you have a hard code waiting to be read and can get that done for free at many places like chain parts outlets but get the #s not the diagnosis as they are nice to do that for free but there to sell parts really.


So. You aren't pleased with this dealer and doesn't sound good so far. What's with your warranty - dealers only? Find another as you took it in for a tune up that was YOUR request by the read not a diagnosis yet. Yes, when an engine doesn't run properly it can kill a converter but shouldn't have so it is or was something else that caused it IMO.


A problem with warranty work is if like I knew it in the stone age (loooooong ago now) at a dealership was they hate it as it doesn't pay well and covered things you had to about prove were the exact problem to get a dime.


That's motivation for some not to jump to do stuff for low bucks. Get the code and post the # and don't wait as you may end up owning this problem warranty or not,
