Landrover Freelander Guru's?

[Serious Offroad]

Having a ***** of a time with my 04 Freelander. Getting error Codes P0301, P0303 & P0305 (misfire) and a corresponding Bank 1 O2 Sensor lean code.
It's intermittant, plugs are new (less than 1k miles).

Totally stumped at this point.

I've gone through the typical steps on all British cars, pulled/cleaned electrical connectors and added a dab of dielectric grease....no change.

Anyone got any insight?

Sell it? Crush it?

what else have you done? Tried swapping coils to a opposite cylinder? See if the misfire moves?
Not entirely certain but I thought cylinders 1,3 and 5 are on the same bank. Ground for those coils good?

My sister had an issue on her car (different model) where it was getting a misfire. Ended up being a fuel injector. In the end it actually just ended up being the injector seal. They replaced them and it solved the problem.

I've been pouring over schematics and tech documents....

I'm considering killing it.....with fire!

Has it gone through the fuel pump recall?

Have you checked for a vacuum leak? What level scan tool do you have or is it a code puller only?

[Serious Offroad]

Checked for vacuum leaks.
Fuel pump recall was performed.
Using an Actron Scanner, not sure of the model but it's a great tool.

I've learned one thing that I'd like to share with you all...
The Brit's couldn't wire a toaster properly.

That was exactly the problem with my sisters car. The fuel injector seal was bad, but not on the low PSI side. It was on the vacuum side, which threw the mixture out of whack, and created a code for a misfire. It was a bit baffling at first. A lean code and misfire is basically either a vacuum leak or possibly a low PSI in the fuel rail.

What a P.O.S.!

[Serious Offroad]

Poured half a bottle down of Sea-Foam it's throat....literally.
Seems to have smoothed out a little.

It's our least favorite model to work on. Really cannot wait for them to completely disappear.

Well I'm a fookin' genius!!
1/2 Bottle of Seafoam got it purring like a kitten...a psychotic kitten, but a kitten none the less.

As soon as I'm able to afford another car this one is outta here.
