Hi,
I've encountered a problem with my Micra, which is only apparent at high revs (only experienced when revving at standstill - not driving).
What happened was: I did an oil flush then changed the oil and filter. Drove it after this for around 6-8 miles. Ran beutifully as I had already changed the fuel & air filters and spark plugs.
Later got home & gave the car a quick jetwash. Stupidly cleaned some of the engine as well. Yes it probably wasn't such a good idea in hindsight.
When I started it, it fired up no problem, but the fuel guage started moving about erratically for a while going up and down. It kept wavering from the right fuel level mark to the minimum mark but not zero, then remained at the lower end of the scale after a while, again not zero. Also noticed that when the accelerator was pressed hard to the floor - maximum revs - (sorry dont have a rev counter) it seemed to 'pulse' that is quickly switching from full acceleration to accelerating with a blip as if not accelerating (like no fuel?)but only for a split second.
This was a couple of days ago and i have only driven the car twice today for around 8 miles (2 x 4 mile journey's).
The fuel guage has stabilised, but the acceleration problem is still there at full revs. It starts and drives OK but does sound a little noisy and a bit like it's misfiring? (NOTE: A BIT but could just be me though?) The exhaust i noted smells a little pungent (smelled? up close) - then again have never really paid any attention to it before.
Any ideas or suggestions as where to start or what might be wrong? I thought that the water had clearly got somewhere it shouldn't have, but would hopefully dry off in time....
TIA.
