96 Cobra throwing PO174 code

[JayDPee]

Hey all. I've got a 1996 Cobra I bought earlier this year and it's been throwing a PO174 since I got it. No noticeable side effects, other than the CIL. Runs fine, no bog, no misfire, pulls strong.

I'm planning on checking intake leak. I've replaced exhaust, cleaned MIL's, and cleaned MAF. Any other ideas? I'm going to work on it this weekend and don't want to miss anything.

Thanks.

Possible 02 sensor, or as you said an intake/vacuum leak. Any exhaust leaks?

If i remember right! I fell off the sidewalk with my car and its dropped. I broke a cat on my car and it kept throwing that code. So it can be a cat or sensor.

Drivers side fuel system is leaning out on ya. Check the O2's and injectors.

If it was a cat you would prolly get a catalyst code like P0430/P0431
