map sensor problems?
Hey all, I'm having map sensor code 0108. van idles very bad tach just jumps up and down and so does the engine. I can't go faster than 45mph. Van lurches forward when stopped at a light and act like it wants to stall. I replace the map sensor twice and replace the tps sensor and still same problem. Funny thing is I can drive the van in auto stick and drive a fast as I want. Also getting black smoke out the exaust. When I put the new map sensor on I reset everything disconneted the battery and everything was fine for a day or two then map code came back. All this happen initially after a gas fill up. 02 caravan 3.8l Getting ready to take it to the dealer before I found this site. Thanks for any help

P0108 (M)
Manifold Absolute Pressure/Barometric Pressure Circuit High Input
MAP sensor input above maximum acceptable voltage
where does it say change ANYTHING? codes do not mean chnge a component....this COULD BE a sensor seeing an out of "range" reading....
low vac = hi voltage.....
>any other codes?
>1st what is ENG vac reading ?
I would look for a vacuum leak. try the old spray trick to locate a leaking area/component.....
