po100- MAF or VOF A circuit malfunction.
po200-injector circuit open.
its a 1996 camaro lt1 with a lt4 hotcam, and the check engine light will come on, one day then the next day it wont until it warms up, or i get on it, its studders, and boggs, and has pretty big power loss. what should i do? it just started doing this like 4 days ago..

 

P0100 = MAF flow system static (static frequency)

The MAF readings are not changing. Key on - check for 12V between the pink wire and the black/white wire in the MAF harness connector. Could be a broken pink wire - a more common problem on the 97's than the 96. If you have 12V at the harness connector, substitute a know good MAF sensor. Clear the code (pull "PCM BAT" fuse for 30 seconds) and see if it comes back.

P0200 = Injector Circuit Malfunction

Key on - check for 12V at the pink wire in each injector harness connector. If you have 12V at each pink wire, with the connector removed, check the resistance of each injector. Should be in the range of 12-15 ohms. If the injectors check out, get a 'noid light and insert it in each injector circuit to verify the PCM is providing a ground pulse to fire the injector.
