Has the check engine light come on? Also, have you checked for vacuum leaks and the EGR?

I need to know what the code is. If you take the car to a nationally recognized parts store, they will scan the computer and tell you the code. Most will do it for free.

Let me know what you find.

I go to the garage today...code : P1337 , CKR2 ,P0141, O2 SENSOR.



I have a b20b engine from japan , intake manifold b18b ....
The guy said probaly the engine need more air (oxygen)Because the b18b intake and injector are little.


My O2 sensor wire are bad or cut?

The guy said I have no cranksensor because the engine was japanese ...he right?

What I do????The guy said do nothing or go to see the car engine installer. I dont want to burn all my money for frankeinstein.

Did you change the engine or intake? If so, that is where the problem is coming from. As far as the crank sensor, I believe he is correct. They are different.
