I have changed the spark plugs,changed intake manifold gasket,smoke tested for vaccum leaks cleaned the map sensor,repaired exhaust leak,changed o2 sensor with a new bosch, tested fuel [email protected] 36psig, changed fuel filter. I cannot go past 40 km the engine light comes on. My scanner shows bank 1 sensor1 bounces between .996 to 1.018 ratio.

Thanks for choosing Just Answer . I'm Wolfgang here to help!!
Below is my first answer or request for more information. If you do not understand it, or you need more information from me, or need me to go in more detail. Do not rate yet, just reply. Put yourself in my shoes, I can not see, smell, hear, feel or touch your car, nor do I know any history on it. So take into consideration I am doing my best based on what you tell me. Also understand fixing cars often requires sophisticated tools, that you may not own. So even if you can not do what is outlined in my answer, that does not mean my answer is wrong deserving to be rated negative.
