96 Z28 p0430 and p0441 help
i thought it was cured when i replaced the gas cap.i drove the car for 30 miles or so and decided to race a civic waste of time haha. i took it above a hundred and service engine light came on and i got the same codes soi replaced the gas cap. cleared the codes they came back after the 100+ mph's i believe if there was a vacume leak it would of came back right after i cleared it and started my car so i am lost on the p0441 code. is the solenoid **** to failure? also got the code p0430 which i think ii have it limited down to either the catalytic converter plugedor the o2 sensor. it does have a full borla exhaust system i dont think that has anything to do with it. but the car does have 144k on it so i am leaning to the o2 or cat but the other code i have no idea. of what to check and look for how to test it so on any help would be nice i hate the light but would like the relief of it gone. but still having it functional. also i am getting a ticking noise probably from a rocker arm if i go roller rockers should i do the rest pushrods lifters ect. its kinda a daily driver so i dont want alot of downtime untile the winter where i am going to be installing bigger injectors edelbrock air gap intake and bbk 58mm throttle body just for starters. also i already have the throttle body would it hurt but still gaining some hp to port the intake i have without doing the injectors or should i wait and do it right.

as far as your 441, my problem was with the charcoal canister... the rubber vent hose to that was loose and it caused that... if you remove the inner plastic behind your drivers side rear wheel, you can get to it..
