check engine light
Ok now that i had my car for about 36hours i have got pulled over once by the cops just wanting to see my license 
and got my check engeine light i now this can be off many reasons but the cars runns normally and has enough water and oil are there any common things that will cause this? i will admit i have been drift but not mutch maybe five times in all and thats in the rain so that might have caused something

It could really be anything, go to autozone or pretty much any auto parts store around you and have them run the diagnostic scanner thing on your car. This will tell you the code that is activated and they should be able to tell you what you will need to do to fix it. And what year is your car because anything earlier than 1996 is OBDI, which they cant scan

you can find the code yourself. pull the ECM out to where you can see the side opposite of the wires. turn your key to the on position and turn the little screw on the computer all the wat clockwise. then wait two or more seconds and turn it all the way back. it'll spitt out a code via flashes.( several long then short) (flash...flash...flash...flash...flash then flash-flash-flash-flash-flash for example is code 55 which is normal engine.) to clear the code at your own discretion turn the engine on then turn the screw all the way clockwise then wait two or more seconds and turn it all the way back. turn the engine off and start the car again. the ECM will reset instantly.
this method will tell you the code and the second part will clear it and the check engine light. i suggest you clear it only after fixing the problem.

took this off another forum
How to check for fault codes by PULS8N(OZ).
The ECCS Control is found under the passenger side kick panel.
The ECU has a window on one side to view a red LED and a green LED - when checking fault codes, a red flash is worth 10, and a green flash is worth 1. So for example, the code to say that everything is functioning normally would be 5 red flashes and 5 green flashes - the code is 55.
The ECU has 5 modes of operation, for diagnostics codes, it has to be set to mode 3.
1. Make sure the screw next to the viewing window is turned clockwise.
2. Turn the ignition on
3. Both LEDs with flash once, then a pause, then a second time, then a pause, etc. etc. up to 5 times then will repeat the process. After is has flashed 3 times then turn the screw completely anti-clockwise. - this will select mode 3.
4. The LEDs will now flash codes. 55 means that everything is normal. The rest are written below.
5. When finished, turn the screw back to clockwise and the ECU will reset itself automatically.
Don't worry about the '5th cylinder misfire' and '6th cylinder misfire' or anything, the codes are the same for all Nissans.

on board diagnostics... the nissan ECU basically... the 95 has a OBD1 and the 96 has the OBDll. The OBDll is a huge pain in the *ss and the wiring in the 96 is completely different from the 95 model
From what i understand, the ODBll is plugged right into a computer, and there's no way around emissions because it detects if anything is missing. It also is hard to mod w/ because the computer will cut fuel/retard timing etc to return the engine to stock numbers if anything has been changed

On-Board Diagnostics. OBDI is the first generation of electronic engine controls, which had no standard for codes or communication with an external computer.
OBDII was mandatory on all US cars in 1996. It provides a standard for codes, external communication, and the type and location of the connector.

so that's a good thing...
how do they do emissions with pre-96 cars then?
