Misfire on acceleration but fine on motorway :-/
« on: 16 November 2012, 17:56 »
The car... an ABF in my mk2  :cool:.

On the motorway it runs perfectly fine
It also runs fine when starting from cold in the mornin, the problems happen much much more when running for 5-10 mins.

Setting off from traffic lights it misfires, sounding like a subaru

When cruising along at 40 in 5th it's usually fine and runs smooth but if i put my foot down it goes into subaru mode and the same happens if the road starts to incline, meaning I have to gear down due to the loss in power

I've heard something about vaccum pipes or something like that might cause this??
Any help would be much appreciated  :smiley:

Sounds like plugs to me.

Can the plugs cause an intermittent misfire though...I thought that would've be an all the time or none of the time sorta thing?

Think I might go get some tomorrow though to see if it sorts it.

Any other ideas if that isnt it?

Yes
And coil. Most likely to be coil to be honest. Common thing on the abf

To be honest i dont think the plugs will help anything but going to do it anyway now ive got em

if it helps...the car turns over fine if i turn it off and back on again but about a minute in then it starts getting lumpy...
