CEL Code: P1103

[Andy123]

While driving towards high rpms the car seemed to jerk a lot. So i figured it was the fuel pump. A CEL than appeared. P1103 to be specific. Waste gate Actuator.

Tried to search up on it but didn't find specific info to whats causing my problem. When turbo kicks in the car jerks a lot.

Just wondering what problems cause this CEL?

Thanks!

kinda sounds like fuel cut and/or misfire.

Well i still have turbo stock. Only mods i did were fmic and an injen style intake. Feels like some sort of fuel cut. But the code says otherwise

Sounds like you either hooked up your Wastgate Actuator wrong or it is faulty. I would replace it. It is not possible to have "fuel cut" when you are running stock, at least not at speeds lower than 120.

Here is a checklist you can go through:

1. Do what is almost free. Make sure you have all of the couplers nice and tight on that cool FMIC. Run a boost leak test. If you use that nifty little search button, you will find out how simple it is.

2. Make sure that the WA is properly hooked up to the turbo, if its too lose or too tight, it will malfunction

3. If you have a MBC make sure it it hooked up properly

4. Wastegate Actuator is faulty, replace it (If the CEL says WA, Its probably something to do with the WA)

Ok, tomorrow ill check it out. Yes the car is all stock other than those mods listed before (i have a mbc but not installed yet) , and the check engine light says wastegate actuator.

if it helps my vacuum gauge reads -18.

i will do a blt. i guess theres no way of knowing unless i make one of those testers.

Bring back an old thread.... Just carious to know if switching out the WA stopped the CEL from coming back on and the fuel cut? I have the exact same mods on my GSX and it's doing the same thing as well. No major boost leaks other than from the fuel injector seals; which I am waiting on them to come in to change out. I did the the free mod thing where I took off that little piece of plastic from one of the snorkels and when I reinstall it, it doesnt cut anymore but the CEL came back on? Don't feel like the turbo is pulling as strong as it should either. Any suggestions? Thank you very much!
