You will need to have the computer reset after having new part replaced, otherwise computer won't read it for 20 starts. Double check for any vacuum leaks. Bad 02's sensors or camshaft position sensor will also cause this

Testimonial: "thanks so much. once we got our new sensor and replaced it and saw no change we thought we were screwed. at least now we know that there's still hope"
