Hello, so where do I begin.. My Micra developed a misfire (I changed the injector and sorted that) but during it's time misfiring it developed a long hesitation when I put my foot down, the revs would build slowly but the car failed to accelerate, then suddenly -as though a turbo kicked in- it would regain full power and pull.
I was hoping it would fix with the misfire but it got worse once fixed. About a week after fixing the misfire I was parked on a hill with not much fuel in the tank and it wouldn't start.. It would turn over all day but never fired up. I filled it with fuel. Wouldn't start. Checked it was getting fuel to the rail (tick) and it wouldn't bump start either... The next morning it started up second time but was cutting out once under drive. (It hated second gear)
I put 2 second hand throttle bodies on and soldered my old one (my old one now works the best) so it ran but was lacking all power.
It also seemed to run better with the air box off.. I replaced the air filter but no improvement.
Next we turned to the carbon canister while looking if pipes were split or blocked to the throttle body. I disconnected the pipe on the top of the canister that ran to the bottom of the throttle body and hey presto! All power restored... Or so I thought...
I took it to work (31miles) and it was losing power again like it had with the misfire but unusually it was always after putting my foot back on the accelerator after I was coming down a hill or turning a corner where the loss in power occurred. There is also a small oil leak which is only noticeable when I'm parked down hill over night.. Could that be anything to do with it?
Please help!
