Ive been getting p 0237 and p 0336,
And just today i had my truck start blowing massive amounts of white smoke and running rough at idle when i "blip" the throttle.

Everything has been fine up until i made the mistake off unpluging the the map and crank sensors while the key was clicked forward.

p0336 Crank sensor signal
p0237 map sensor low
do you still get the smoke and rough idle when you cycle the key. or is this a problem from before. is that the only codes?

the sensors mistakenly were unplugged over a week ago. i dont know what started this.
all i know is the light went off and it came back on within 5 mins when i tapped the throttle at a red light.

did you clear the codes? did the same codes come back on? sounds like you might have a bad map. i'll check the diagram and get back with you

cel light went off, but i can make it come back on.

If im in neutral and i "blip" the throttle a few times it will start blowing white smoke and the Cel will come back on.
