Edited by ukat3731 on March 4, 2016, 9:12 pm not sure how help full this may be but interesting , does the scan tool map sensor reading match the mitivac? if you had any problems with the throttle/ pedal you would have a code for it no?
kia do a engine where the crank reluctor moves, and gives the same symptoms you describe .
i chased this fault for ages it gave good vac readings inatialty then went down to 10 in hg .
with a low vac reading the engine will be running very rich, can you create a reading of 18 ing with the mitivac on the sensor to see what the pcm does with the throttle body ??.
