MMII-Z-XXVIII

I just installed pacesetter long tubes, texas rumbler X true duals with 18 Dynomax bullets (((Rumble is an understatment)))) I have o2 sims in the rear and extensions in the front. So far thats the only performance mods. I got an SES with these codes:

P0412- Secondary Air injector valve
P0412- Secondary Air injector system valve A malfunction
P0418- Secondary Air injector Relay
P0418- Secondary Air injector system relay A malfunction
P0135- O2 sensor heater circuit malfunction B1 S1

Could this be caused by a bad o2 sim plug? I removed the necessary relay for the AIR system should I have left it in?

Try plugging the relay back in, and resetting the computer. This might help. When I removed my Air, I left the little relay plugged in, but unplugged everything else. Now i have EFILive and I just totally disabled it.
