I need help diagnosing a small misfire on my 94 wrx wagon, it is constant, tick over or at revs, any temp, etc,
Can all you in the know please list on this thread the probable causes of this please, the plugs i have done already, any help appreciated thanks, i would like to get this sorted before next weekend.
I assume coilpacks are the most likely problem?

 

What condition are the spark plugs? What are they gapped at?

 

they are new plugs, standard gap, ngk pfr6b

 

I would say change your coilpacks next, is it smokin or any preasure on the coolant pipes?

You need to find a decent Mechanic around your side, API are just down the road or Autosportif are also good but make sure you take ££££££ with you

I'm also in the Oxford area so let me know how you get on,

 

sounds like maf or a coil pack go through your coils one by one unplug one at a time if it goes away you have your answer??

 

mmmm, tricky one this misfiring methinks, maf first, and then 4 new coilpacks , just as i thought, thanks all

 

hi i have the same problem,when ticking over the revs go up and down and the perfomance has gone.so did you solve this?and if you did what was it.what do you think mine is.????and what is maf??help wud be appreciated..thanks
