i noticed that the sensor on this website http://www.autopartswarehouse.com/de...USOS-1000.html doesnt have the plug at the end its just wires
is that still ok?
and should i try to fix it as soon as possible? or just take my time with it?

 

That o e is a universal plug like I mentioned above. You cut the connector off of your existing sensor and splice it on. We have used those on a 30v with great success - don't sweat using one. As for the gas leak code, yes if you didn't seal the tank well enough (you really have to drive that locking ring on hard and make sure the rubber gasket is in place) it absolutely could be the cause. When I said to reseal the cap, that was poor wording - I meant to make sure it was on tightly. A loose cap can trigger codes.

 

thanks a lot guys i will do my best in fixing my baby

 

Yeah, the primary o2 sensor should be the easiest one to replace since it's out in the open. As for the fuel code, always remember to tighten the gas cap enough until it clicks about 5 times when you fuel up. If that doesn't fix it, maybe you just need a new gas cap.
