Getting p0305 and p0305p.

Question

I have replaced fuel injectors, distributor cap, rotor, coil, oxygen sensors, tested fuel pressure - ok, tested compression - good, what shoud I check next?

running somewhat rough, but okay. Check engine light comes on within 5 minutes after clearing. Also changed out cylinder 5 spark plug and wire. What next?

Answer 1

Hi there,

Next step would have to be a leak down test on cylinder #5, you can also check for an intake manifold gasket leak. Either could show a problem without a compression test showing a concern.
