misfire

hi guys i have a 2002 vogue just started to get slight misfire when doing about 25 to 30 mph i have changed the plugs but to no avale should i buy one coil and try ech one till i find the fault or could it be something else if i put it on disnostics will that find the problem as it doesnt misfire all the time cheers

get a mirror and put it at the back see if you have any arcking from the coil. is it when it cold or hot? or both..

when warm

there are a few things it could be, you need to look for arcking across coil or leads make sure leads dont cross and are all in there clips. after that look at maf senser. dont go rushing out buying bits you may not need..

cheers got a mate u got disnostics thing getting it check mates rates see what comes back from that then start checking the bascis cheers

Have a read of my thread here. The upshot of it all was a corroded connector..

is yours fixed now then

For sure.
