I have a 1988 nissan 200sx xe and the EGR keeps sticking. How do I clean my EGR

Take it to a alignment shop they well in California usually charge $45 to $75 and trust me its not something you want to attempt on your own.

check coil

Is this the 2.4L? If so, I bet the Exhaust Gas Recirculation (EGR) valve passages are clogged. Likely has 3 of 4 EGR ports clogged, sending all EGR flow to the #2 cylinder. Check if it still has 8mm plugs in each runner for EGR transition passages. If so, remove those plugs to clean the EGR passages.
Hope this helps. Good luck!

I think you should buy repair manual first for your vehicle after that it will be easy for you to solve the problem. Check the link may be you will get something useful here 1988 Nissan 200SX

We have two Nissan 200sx's, a 1995 manual and a 1996 auto. Both had this problem and both turned out to be the same thing. The "idle air control valve." It was most noticeable if you ran the air conditioner and then came up to a red light. You would have to keep pushing on the brake and race the engine a little to keep it from shutting off. Replaced that part and both cars have never had the problem again.

This diagram shows the location near the middle of the vehicle.

This is a common problem. All of these work from a printed circuit board. With vibration and age they will eventually get a short in the board. No one repairs them just replace the instrument cluster. Requires removing the front of the dash to remove it.

its a one banger you **** ****!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

fuel filter also if it has a pump in the tank you should keep at least a fourth of a tank of gas because the gas is what keeps the pump from over heating also check the fuel pump relay and the oil pressure switch because if the oil pressure is to low it stop the car from running to keep from blowing it up .

The the airflow meter can shut off the car completely, it can also stop the car from reving over 2000rpm "limp mode" to save the engine from getting un-measured amounts of fuel.
