    New VX Owner and Rough Idle

    Hello All! I just bought myself a 99' VX. Had it shipped all the way up to the island in Alaska, in which I live. I have never seen such an awesome looking vehicle. I just had to have it. I like everything about it, with one exception. It is idling strangely. When put into park, the tach flutters dramatically, and often dies. Three days after I got it, the check engine light came on. The dealer says there was never any kind of problem when they had it. I think he's lying, but that's what happens when you buy something sight unseen. Anyway, I was wondering if all you seasoned owners had any tips for me. I have read several reasons for the check engine light to engage, but the idling is baffling even the local mechanic. I don't want to ever drive anything else. I hope it isnt serious!

    **edit** Welcome! I moved your post into it's own thread so, folks can answer your questions..

    If you don't have a code reader get ye self to a local AutoZone as they'll pull codes for you. Also, try disconnecting your battery for about 30 minutes so the ECU will reset.

    Rough idle is generally indicative of a fuel issue and sometimes ignition. You may have something as simple as a loose sensor connection or perhaps one has failed. If that's the case you'll definitely have codes.

    How does it run when driving? Does the power feel normal? Is the only problem you're having with the idle?

    Keep us updated!

    Welcome to the club ! I myself have '99 with rough idle. I've heard the intake gasket needs replacement. Depening on the weather/humidity conditions it will act on you. I've heard it is $200 repair. Good luck !

    I would definately look into the intake gasket as others have mentioned. Other little things to do may be change the fuel filter, spark plugs, clean/wipe down MAF sensor in intake. But if you can get the code read we can probobly help more.

    BTW... Which Island in Alaska?
