Working on a Ap1, and the car is running extremely rich. At idle the injector pulse width is 7.75ms. if im correct, isnt pulse width suppose to be around 2-3ms? let me know what you guys think. thanks!

 

it could be the map sensor. try hitting it acouple times with the plasic part of a screw driver (map wak) if that doesent help u might need a new one

how did you get this injector pulse width reading with a scan tool or a scope ???.
can you get other sensor readings as well, it's really easy to diagnose a car if you have a scan tool.
could be a bad A/F sensor or coolant temp, i have never seen a honda map sensor go bad.

 

I have seena Honda MAP go bad, and this looks pritty classic MAP sensor failing.

 

lol...thanks guys...good replies. Did a dummy move..oops.. The harness connector for the map and the coolant are the same pin and size. i had them in there wrong locations. i was lookin at the etm, and i relized it. Also. i have the HDS so yeah, thats were im getting my readings from.
