[SazonSerg]

Hello guys in need of help

I had a misfire on my gst p0303 car drove like ass and it also had one code before that p1105 but it ran fine so they changed the coil pack and the misfire code went away but not the p1105 and the car sounds like shit

I will post videos they also said my fuel had water so we drained it and put dry gas and still same sound

I don't think the P1105 code would effect the motor running. This code is for the fuel pressure solenoid and is to help with startup. Here's the troubleshooting guide from the FSM.

You haven't said what tests you've done to locate the running problem. You should start with doing a boost leak test. You stated this started after a backfire. To me it's possible you blew a coupler loose & now have a boost leak.

I haven’t done a boost leak test but I will check up on all of that thanks again
