hi guys im new to this site but i needed to ask why my holden vt 98 model is running rough after ive just done a major service, replaced spark plugs, leads, oil filter, fuel filter, oil, and after i done all this my car splatters real bad on take off or when i put my foot down any help on this matter would be much appreciated.
leads are connected properly and plugs n leads are new, well ive done 10,000ks sence i put them in but ive had this problem sence i changed them.
Have you checked you didn't crack a plug when you put then in? If not plugs maybe a vacuum hose is loose, check all the hose connections for tight fit or cracks.
Definitely check for a cracked or closed up plug, its easy to crack them when tightening them. Also double check the plug leads are on right plugs/coils. If theyre wrong, they will cause the car to splutter and run crook.
