multiple obd codes p174, p304 and manufacturer code p1744, it all started with vacuum leak ready to burn
the vacuum line for the intake manifold came off and then it started throwing the p174 and p304 codes, I have changed the fuel filter some of the egr vacuum lines and changed the plugs all that, took a trip to California and when I got back to Nevada it started running like crap and I put it back on a code reader that's when it threw the manufacturers code for the tcc solenoid. I also put in a new throttle position sensor because it seems to be how the throttle is pushed, it is driving me crazy, im a girl but after this I will be able to rebuild my car. last time I let someone get under the hood they put rubber cement glue on my egr vacuum lines and now I am replacing them please can anyone help me. sometimes it acts like its starved for gas while smelling like its flooded.
