clio 172 cup/mk1 xr2
have had my clio 172 cup for several years now and is starting to show its age, have had an ongoing problem with a misfire changed plugs was ok for month or two then started misfire again got new coil pack but no difference, changed plugs again and bought magnacor leads lasted ok for another couple of months, so took it to a local performance garage and they said the compression was fine but they said the leads were at fault causing an arching and they have seen problems with magnacor leads before and advised standard ones so they put silicone round magnacor ones to make better seal and put plugs in all was well for another month now doing it again, they also pionted that a fault with two relays and that my throttle body may need cleaned but this wont cause the misfire. can anyone help or advise renault specialist in scotland. thanks Brad
