Hello, I have a 2000 infiniti i30 and it hesitates and spuders sometimes with a light smell of gas. It does this at the beginning of using the car and it sometimes has a flashing check engine light as I accelerate, but then it stops and runs fine the rest of the day. I do have a code reader and it states the codes P1320, P0303 and P0420. Also the evap sys. Is present showing a malfunction. Thank you

The 303 code is a misfire on #3 cyl which really can be anything from a spark plug to a sensor bad or something more serious. A pro should diagnose this one as they are very hard to find what is causing the misfire. The 420 code is a bad converter or exhaust leak prior to the converter. In your case it is probably the converter due to age and mileage it cold be an air leak prior to converter as well but I would suspect the converter more. The 1320 is a coil problem which goes along with the misfire. If a coil is bad don't be surprised if you have ot get all the coils replaced and they need to be Nissan the aftermarket ones just don't do very well in these models. For the evap it may be the solenoid on the canister purge but should really be smoke tested for leaks and to find out where the problem is. Your best bet to fix this stuff is to go see your local pro and have him go at it.

Ok but at the moment I'm a little tight with money so basically I fix the car my self and since I know how to handle my self ( I was training in a school to get my certification for auto/tech and I worked in a garage for 3yrs), I was wondering which of the problems I should handle first.

Try the 1320 first as it may take care of the 303 when it 's fixed. But you will still have converter and evap codes unless you find the problem with evap.
