I bought this motor its quite old 1993 plate Micra 1.3 Super S - it runs fine, but occasionally for some weird reason, when i drive it aronud for quite a while it suddenly start jerkin the car back and forth - kinda like the engine is cutting out or something. It happens more if you accelerate harshly....and it happens in every gear (even 5th).
I first noticed the problem as I was driving the car back from Sevenoaks to my house near Luton.....it was fine for the first hour or so, but then we stopped to switch drivers, and my mate started driving it and it starting jerking back and forth again.....im unsure...
My mate reckons the timing chain may need replacing, as it hasnt been done for a while, but another friend rckons it may just be a dirty air valve.....
It seems to happen more the longer the car is switched on for. I has previously misfired apparently...
I don't think its teh clutch plate as tehre would probably be a problem every time i changed gear right? Any ideas?
Thanks,
