90 240sx seems t o only be running on 2 cylinders

[forsaleNY]

I just had an overheating problem blew 2 hoses and had them replaced. All of a sudden it seems to b only running on 2 cylinders. It stalls if i dont have the foot on the gas and there is a clicking noise coming from the engine when it is on. There is also a strong gas smell while running. im trying to figure out the problem so i can describe it to others so i can sell this vehicle..please HELP...thank you

with the engine running, pull one fuel injector harness connector at a time. note the difference in rpm. if there is no difference, then you found the cylinder that is giving you trouble.
