OK then my supercoupe has a wierd problem .. it starts and idles around 650 idles decent but feels ROUGH at idle liek its shaking... and if the engines cold and i starte h car after aobout 3 seconds the CHECK ENGINE LIGHT comes on.. the revs JUMP to abuout 3K then come back downsomtimes doing this 3 or 4 times before staying down .. the CEL flashes as it does this it doesnt stay on long..


pulled the codes and got a 112 i belive.. the book says its Air intake charge too cold or sumthing but shoudlnt the car be MADE for that ad not produce a CHECK ENGINE ??????

Possible thoughts are BAD bmottor mounts
clogged cats (as the boost SOMTitimes spikes a bit)
on teh key on engines running test i Got only one code 411 Computer CANT CONTROL idle at low RPM
 
I think your air charge temp. sensor might by foobar'd. Does it fix itself once it warms up? Or did you wait that long.
