Ok here is the story. About 3 months ago I was having the engine power reduced problems constantly. Drove with the air box mod for 3 years so I bought a really clean used MAF sensor and changed the air filter. It has ran great ever since. Now out of nowhere it is doing it again and does it 10 times as much when my AC is on. I have to be easy on the throttle because once I give it a tiny bit of gas it goes into limp mode. Just ran a cheap scanner on it and got a MAF throttle posistion correlation code a system to lean code and a Bank 1 sensor 1 O2 sensor code. Also got this weird code. P1182 which is a DTC code. Also when it is running and doesnt go into limp mode it if I hammer it, it has **** for power and over 5k rpms it feels like something is holding it back. Any ideas?

btw its a 06 LSJ

 

Any advice guys?

 

Not to sure if this will help but my car got reduced engine power once so I immediately took it to GM they did some tests then they replaced the catalytic converter for free. It was under warranty. Havent had any problems since.

 

I dont have a cat. But thanks!
