ECU code 45!

[jitaga]

A couple of weeks ago i was lowering my 00 civic SI, finiched the job and when i turn the car on to go test drive it, the car almost died at iddle. When the car is running it runs perfect the problem is when it come to a stop it wants to die, it doesn't but almost, after striggling for a bit it iddles ok (900rpm). The check engine light came on about 3 days after. The code reads 45 SYSTEM TOO RICH OR TOO LEAN. I already checked the spark plugs (platinum +4 bosh)and they look ok, I relace my MAP sensor for a new one and nothing, please help any suggestions are welcome. also is it possible for a o2 sensor to fail from one day to the othe????

well thats one problem, the bosch plugs suck for hondas, but just search to find a cure for too rich or too lean

...

the car was running ok for a couple of weeks with the new plugs, i did search all over the place, what can you tell me about the o2 sensor?

According to he service manual, the probable cause of P0171 and P0172 (code 45) is Fuel supply system, Primary Oxygen sensor, MAP sensor, Contaminated/bad fuel, valve clearance, and exhaust leakage.

o2

you guys think that is possible for the o2 sensor to fail right away?

o2 sensors are very tricky, one little bump could mess one up. When I hit the Jetta way back when, the jolt from stopping knocked my o2 into an early death.

i would check your o2 sensor and fuel regulator?

 

[jitaga]

check

is there a particular way to check if the ruel regulator is working properly, same with the o2 sensor??

looks like lowering your car really does add horse power.
