174 could be a vacuum leak, low fuel pressure or a bad mass air flow sensor.

How do I check for these possible problems without have to take it to a mechanic

You need a fuel pressure gauge, and a scan tool to monitor the long terms. Not really a job for home. At least get a diag to confirm the failure as guesses are expensive and most of the time wrong

Don't know if this will help but when I fill my car up with gas my ce goes off

With the 174, it should not effect it.

So turns out I have a leak at flexpipe infront of my o2 sensor. I was wondering how do I know what kind of cat my car has? Or if I could put a aftermarket one on with my oem exhaust? My flexpipe and cat are one assembly. Thx
