So what you are saying is that I could buy any OBD II scan tool from an AutoParts store and that is all I need? My buddy said I may need a certain attachment or card to read Isuzu codes. I just wanna make sure I get what I need the first time around since I am now 100% bicycle ridden.

And so, in the last hour, I went back to the parking lot with my buddy who is pretty much a mechanic, but mostly with Dodge, Jeep and Ford trucks. I disconnected my battery for a few minutes and then reconnected it. Initially after I restarted the CHECK ENGINE light was off. Both my and my friend agreed I should not leave it in the parking lot (its just begging for trouble in Chicago). Its really only about half a mile from me to the store so I idled it home, giving it only a teeny bit of gas as needed. The CHECK ENGINE light came back on solid after about 20 seconds. Then it flashed 20 or so times and went solid again. It did that 2 times and then started flashing continuously.

My VX is now safe in my garage for the moment, but I am not sure where to start.

My friend said he thinks it could be any of the following problems:

1) Bad O2 Sensor
2) EGR
3) Spark plugs need changing
4) Intake Gasket

So my question now is, should I buy a scan tool or would I be better off just getting her towed to a mechanic and having a full tune-up done and what not since I am at 30k already.

I do not know how difficult it is to clean/replace my EGR Valve, nor to I really know what it even looks like. I'm gonna go back and read some more previous posts and also peruse the manual.

Any additional help is much appreciated. I am very angry and depressed about this.

Thanks - Bart

PS - On a lighter note however, there is a good possibility that I have finally landed a job out west (Reno, NV). I will find out Monday or Tuesday if I get the job. If I do get the job, I will be needing to drive out there from Chicago within the next few weeks, so better this happening now than in the middle of a corn field in Nebraska. So, I'm trying to stay positive .
