HELP! The VX won't stay running

[CrnCnn]

The VX will start but then when i try to put it into gear it will die! what would cause that? We already replaced the Mass Flow because the "check Engine: light came on and that was the code they gave us. But now this. HELP!!! PLEASE!!!

...that sucks. Let me know if you wanna work on it together.

Also, look at this thread from a week or so ago. I think climbcovey was/is having the same issue. Maybe you guys should compare symptoms, etc..

Does it happen all the time? Mine occassionally has issues when it gets really, really, really cold where it likes to stall when I don't have my foot on the gas, OR it'll idle too high when I first start it up. Once the temp goes above 32F or so it goes away.

Check that you securely fixed connector and if it securely fit check the wiring. One day I forgot to set plug back to MAF and the behavior was exactly the same.

The problem is intermittent, but often enough to anger me. It will happen one day and be fine another. sometimes at idle it will act like there was a vacuum leak the RPM's will go up to about 1k then down to about 200. It will die occasionally when stopping or if you let off the gas, an example of this would be in a parking garage, coming down I didn’t have my foot on the gas at all, as soon as I start turning or apply the break... Dead... put it in neutral to restart then next turn ... dead... VERY aggravating. I have read most cases of this have been fixed by replacing the fuel pressure regulator. Given that its not 100 percent I don’t want to dump another 100 dollars in it and still have the same symptoms.

Clint, let me know what you do next, and if you decide to look for a mechanic. I am still trying to find a trustworthy, Isuzu friendly shop here in the Reno area. I need my bearings repacked, brakes and rotors changed and depending on how things pan out, possibly to get this coolant leak looked at.

I love my VX, but man, its a full time job keeping her up to speed.

GRRRRRR from me too.

Erratic idle symptoms that I have noticed should always start with a good idle control valve cleaning. There are a few threads on performing this easy operation. Plus its free to do, which always makes for a good start.

Mine was doing the same thing, very erratic. Run fine one day, die quietly the next until one day it just wouldn't stay started. I replaced the idol control valve and everything has been great since. Its an inexpensive part, around $50.00 and a 10 minute start to finish install. Good luck!

Guys

First let me say it feels good to talk with other people who share the same problems as I do with my Vehicross. You guys have no idea how many times I have asked people about my problem and they have looked at me like I had 3 heads. Or mechanics that have no idea how to deal with this issue because I drive a Vehicross anyway.....

I don't know much about cars so you are really going to have to spell this out for me but the problem described here is the same one I have. One day the car runs fine the next not so good, when I let me foot off the accelerator the car turns off, it will rev up really high when I start the car it will rev up and down on it's own at times. So how did you finally fix the problem? Please spell it out for me because again I don't know much about car parts. Thanks
