remove the black plastic spark plug cover on the top of the engine,you will need at least a 6'' extension bar to reach the plug.number four is the furthest away on the right.
put a standard plug in and check code reader for miss fire. i would advise you change all the plugs to NGK platinum for optimum life. |

finally got around to this, have had no problems with a misfire but its time to change them anyway, just over 60k now.
Problem is that my wrench doesnt fit down the hole! Can anyone tell me the size socket and wrench I need? Then im sure i can find one. Also someone mentioned ngk platinums, where is cheapest to pick them up from? Many thanks |

10MM extended socket and 6" extension bar needed, I changed my plugs today. I have had a few problems with the car like missfire No2 cylinder, then the engine management light coming on then going off when i put a better grade fuel in only for it to come on again so I changed the plugs and two HT leads, WOW engine management light went off so I pulled away gave it a bit of gas UUmmm no problems so I wellied it Fantastic no lights on the display and not a single hic burp or f@rt, Sooooooooo happy now, I hope you get yours sorted, the old plugs were champion( garage man says they are cr@p) put in NGK.

you dont need to use a magnet if youve got a spark plug socket. thet have got a bit of rubber inside the socket so it grips it when you pull it out

Following this. I have a ZR 120 that is playing up, it's fine on tick over but misfires under acceleration up to 2500 rpm, the misfire then goes. I've tried everything and can't find the problem.
I have just been told that it might be a bad injecter not atomizing the fuel correctly. Pete. |
