help with Codes 4, 5, and 14

Im throwing code 4- crank angle sensor, code 5- MAP sensor, and a code 14- Electric air control, this morning when i was on my way to school i was sitting at a light and my car dropped down to around 500 rpm and started to shake and studder and pop really bad, so i pulled over and when i did the check engine light came on so i shut it down because i was kinda wierded out by it, but then i when i cranked it back up there was no check engine light and it was running fine all through the RPM range the rest of the way to school (about 15-20 miles) untill i got into the parking lot and i was sitting there with the car running and it did the same thing the rpms dropped to about 500 and it was shaking and popping, but when i would rev it up it would rev smooth it was only happening when it was idleing, then after school i drove it straight home taking it easy and i was sitting in the yard and it started to do it again and the CEL came on again so i shut it down and checked the CEL and came up with those codes, code 4 is the one im worried about the crank angle sensor, what could be causeing that?

Try cleaning out your distributor firstly. Dont get the TDC sensor mixed up with the crankshaft sensor.

As for code 5, it can be directly tied with code 14, EAC.

(Either 1 of these 3 codes can cause low speed and idle problems)

Try cleaning the dizzy first, look for crust and gunk buildup, then let us know if codes 5 & 14 blip back up.

Good luck J.

It is possible that you could have skipped a tooth on the timing belt as well, jus throwing that out there for you to consider.
