Right so, i have this 04 acura tsx throwing codes p0300 p0302 p0303 p0304.
ive replaced all four coil and plugs (oe plugs),
all four injectors, both camshaft sensors and the crankshaft position sensor. And the codes still persist.
the car is only firing on the first cylinder. Shakes as it should on one cylinder. At this point i need some outside help. The motor in the car has about 35k miles on it. Any and all suggestions would be greatly Appreciated!

 

Can you tell me where the crankshaft position sensor is located? I cannot find it and haven’t had any luck finding this info online. Thanks!

 

It's located by the crankshaft pulley.
Remove the passenger front wheel.
Look at approx 10 o'clock position on the outer edge of the crankshaft pulley.

I changed one on a Honda Accord in about 15 minutes. Took longer to remove the wheel than it did to remove & replace the sensor.
