Inconsistent CEL 1995 Acura Integra

[Dylan Shrout]

I have been getting a Code 42 (Fuel Supply System) on my 1995 Acura Integra. There have not been any noticeable performance issues with it, but the CEL comes on every blue moon or so. I could drive it around for a bit until it gets to operating temperature and then it comes, make a quick stop, get back in the car and it wouldn’t come on the rest of the trip. Some days it doesn’t come on at all. As far as what I have done to fix it, I’ve replaced the O2 sensor and the fuel filter. I don’t want to keep throwing parts at it, especially since the inconsistency has me lost with it. I’d greatly appreciate any pointers! Thanks!

I would start with 2 treatments of BG 44K or Techron.
