I am a recent and first time owner of a 97 z28. I am getting a P0403 & P0443 codes. I know they are EGR & EVAP faults. I have checked and changed any vacuum lines I feel to be suspect. I have replaced EGR VACUUM SOLENOID and EVAP CANISTER PURGE SOLENOID VALVE. I not sure if im just being extra paranoid but I get a wiff of gas fumes now and then.. Any input from you pros would be great!!!! STILL GETTING THESE CODES!!! When i start moding i hope to get these emission stuff tuned out.

Both codes are specifically for the electrical circuits to the solenoids. The code can not be set by problems with any other part of the system like the vacuum lines, canister, EGR valve, etc.

After you replaced the solenoids, did you clear the codes (pull "PCM BAT" fuse for 30 seconds).

Did you check the fuse for the solenoids?

I tried to reset onlyby disconnecting the negative battery terminal. Is there another way? Is the fuse located in the compartment under the Hood or in the car under the dash?
