High Idle at 2300 rpm and dumping gas

[mybirdcanfly]

Did get another MAF and no change....and the VX actually seemed to run a bit better with it disconnected....more reason to believe the computer?

Been online for hours still can't confirm if there is an ignition control module and a computer. I called Isuzu and they said a computer is $800 but I can't believe the main computer would do this....possibly an ignition module?...in my experience such things either work or not.

You've already spent a bunch of money with no results and you're just guessing trying to fix this problem on your own. There's an authorized Isuzu Service Center at an old Isuzu dealer over in Wayne, NJ. It's now Maroon Kia.

They'll charge you a lot for labor, but they may have someone who knows these Isuzu engines and can fix it quick. They may have an Isuzu Tech2 Scan Tool and find the problem fast. I don't know this dealer and they may be a bunch of bums looking to steal your money, or they may fix it in one day for not much money.

Call them or drive over there and tell them your problem and ask if they have anyone who can track down this problem. Then make a judgment call on whether you want them to work on your VX.

The intake gaskets are a possibility. It's more involved than changing the sensors you've done so far. It's up to you. Keep trying on your own, or find some good professional help. Good luck whatever you decide.
