I have a 99 ponti sunfire 187k miles 5 speed

I have a 99 ponti sunfire 2.4 over head cam 187k miles 5 speed manual shift. It idles at 4k in neutral and accelerates on its own. This started out of no where a cpl days ago. I had some minor issues that no one seemed to think important, the check engine light is on always and comes back as an evap code but everything is clear It has been on for the 5 yrs I have owned the car, they clear it give me an inspection and Im on my way, then it pops back on a cpl days later...then my ABS light started popping on at 56 MPH, the odometer light blinks and flashes the numbers around, but then goes back to normal...the local mechanic wont touch my car for any amount of money...I have had another mechanic trouble shooting it for almost 5 hrs now...any ideas?

Sounds like either an evap system leak, maybe intake gasket. While it is running spray water around the intake, if it starts to cut out..you have a leak. If that doesnt do it, I would check the mass air flow sensor, and throttle postion sensor. Hope this helps.
