p1174 and p0455

I keep getting 2 codes coming up on my 2006 Saturn ion. One is P1174-which I read to be Fuel trim cylinder balance malfunction and P0455-Evaporative Emission System (EVAP) Large Leak Detected. I have replaced the gas cap, the Purge Solenoid and the Vent Control Solenoid. Upon doing this I noticed my Fuel tank pressure sensor looked loose, so I took that out and cleaned it up and put it back in(there was dirt on seal). I reset codes and so far P1174 has come back on. What do you guys recommend doing next? I don't want to replace tons of parts to find out it was all one thing. Thanks in advance to everyone for the help.

did some research on this for you. the p1174 might be related to a couple of things from bad injectors to MAF or O2 sensor.

what are the specs on your car? 2.0 S/c , 2.2 , 2.4 ???

from what i looked up it could possibly be an 02 sensor/ cracked exhaust or a clogged fuel injector. google search is your friend.
keep us posted

There is a TSB for P1174. Basically there are revised injectors and a ECM update.



Q: What's the difference between a bolt and a screw?
A: First, you screw. Then, you bolt.
