Micra pinking :(

[CMF_panda]

hey, been a while since i last posted, anyways. my micra (2002 1.0 GX UK model) has been running badly, its been bad on fuel and has very little performance compared to our old 1993 1.0L model. I have tried lots of things to try and fix this, i removed the gauze from the throttlebody and it made it a little better. I am quite concerned now as at idle, the rev counter moves up and down as if its hunting for air. My dad says he can hear the car pinking (firing before its supposed to) and that it could possibly be timed wrongly. I was wondering, with it having a timing chain, can it be adjusted, also maybe its a tensioner gone? any advice or suggestions would be great,
thanks,

panda.

The timing can be adjusted by twisting the distributer.

If you have bad idle and its pinking then it sounds like it could be a timing problem, best to get a mechanic to sort it unless you have the kit at home to do it.

there is no distributor on the 2002 k11. so it cant be that. tb were revised so it shouldnt be that. could be best to let nissan plug it into there diagnostic computer. costs about £17.

^^Yeh

Sounds like some crapped out sensors.

Possibly a crank or cam angle sensor giving bad timing readouts? Or even an O2 sensor in the intake or exhaust giving it the wrong fuel maps...(even then i suppose the ecu should be running limp mode - giving sh!tloads of fuel so it DOESN'T knock/ping while you try and limp it home and to the nissan dealer.

i suppose i'll take it to the dealer and give the diagnostics a try if its only £17 thanks alot for the help and keep those suggestions coming.

Do it sooner than later.Pinging means pre detonation which will kill your motor quicker than anything else.

To be honest you dont need to take it to nissan for them to plug in the diagnostic stuff, any decent auto tuner place should be able to sort it for you...
