I have an 87 hond crx fuel injected. It recently sat two weeks while I moved the battery to the rear of the car. Whether my problem is due to that or not I am not sure. I clean the plugs air them out and start the car it runs about 30 seconds to a minute, then dies from getting flooded with fuel in all four plugs, and wont start again til I clean the spark plugs again. It cant be the injectors because the wouldnt all fail at once. Timing is perfect. Brand new o2 sensor. It is also running extremely rich when it does run. What could be my problem?
