Ok got a 306 1.6 TU5JP (I think that the code) Went to Halfords today to get some new spark plugs and get oil and filter for the service. Changed everything, except i brought some fancy exspensive spark plugs(champion Xeon?? Ion??? ZON?? something along those lines cant remeber)
Anyway now when accelerating in third or forth from about 1300RPM theres a hesitation (juddering) that clears after about 2200RPM. Now I know I brought the right plugs for my car, so Why has this hesitation suddenly appeared?? Are these plugs crap? They cost £20 so I thought they might be quite good. Any one had a similar expierience? Or is it going to be a case of buying new spark plugs (the normal cheapo champion ones) I've just given it a bit of a caning to see if it would clear but no its still there.
Any one any ideas??
Thanks
