gotta remember though, that when the neon runs in "barely friggin runs" limp mode.. it does kinda sound like timing is off.
ive worked on a couple cars and forgot to plug the map sensor in, started it up, and it would be all choppy and could barely hold an idle (if at all) .. plugged the map sensor in, viola! problem fixed.

now.. if the timing was off - you *should* get a code 11 because the cam pos sensor and crank pos sensor are no longer in synch. but you arent, correct?
if it was a bad map sensor, youd get a map sensor code.. but you arent, right?

gotta multimeter? a scope would be awesome, but i dont think ya got one, cuz if ya did you wouldve mentioned checking the sensors with it heh.
i can see about comin out possibly tomorrow to look at it if ya gotta multimeter/voltmeter (id bring mine, but its kinda unusable at the moment)
