Today i changed the "Intake air themosensor" and relocated the Air/Fuel meter wire to ECU. After i done and start the car, the car run like a ****... It run really rough, and a lot of smoke coming from the exhaurt. The smoke smell like alot of fuel are not burn yet, and remember is not black and blue smoke. Then i turned off the car and check the engine light. I found Code 11 and 16 are gone, but Code 5 (knock sensor) came on. Then i go unplug the Air/Fuel meter wire from the ECU, and then clear the code and run the car again. But unfortunitly, the car is running the same thing with alot of smoke and bad odor.

Is the ECU problem ??

before i change the intake air themosensor, the car is run great.... should i change back with the old intake air sensor, will that help ????

 

Did you check your map sensor hose to see if it is attached, both at the sensor and at the UIM??

It sounds like a A/F problem. Are you sure that the A/F cable was not damaged? Maybe your ecu is not reading the O2 sensor because a problem with the wire, you can check the O2 sensor output, look at the workshop manual.

Once something similar happened to me and the problem was the hose that goes to the map sensor, it was loose.

good luck,
