ive re-read the problem (you posted) are you sure all 4 are firing? what are the plugs like, are any HT leads damaged or broken, and have you had any plugs off.
also has anyone adjusted the co adjuster or the fuel pressure regulator
all 4 plugs were new and all 4 leads were new aswell,also replaced the coil pack aswell,the fuel pressure regulator still had the cap on so hadnt been adjusted,i removed the cap and if i adjust it it makes a little bit of difference,the co pot didnt hav the cap on it so cud hav been adjusted but if i adjust it it doesnt make any difference atall
