i was wondering if anyone could shin some light on a problem im having with my 93wrx,she wont tak shoe,when you accelerate she starts spluttering and miss-firing,i tried the black connectors but to no avail.have any of you had similar problems,or any sugestions,they would be more than welcome. befor the trouble started,if i drove her on there seemed to be flat spots up high,like the cluthch slipped or something.im without my car with 3weeks,and any man with one knows thats far too long.

 

could be the old 'coil packs' gone. they are prone to show up / cause missfire etc when pushed or at high revs. they only real way to prove it is to swappen for a new / borrowed set!

where would i find them Steve,im a bit of a novice to this crack????????????

 

Depending on what year your car is, they are usually sat on the intake manifold with the 4 spark plug leads coming out (2 going left, 2 going right). bit black block usually.

obviously, it could be loads of things other than these, but if you do a search on coil Im sure there was a large thread about it not so long ago.

On the early cars you have coil packs which you'll find on top of the spark plugs!!

On the later cars (MY97&gt they have a coil on the manifold and HT leads to the plugs (like most cars)

Red,
I would suspect it to be your coil packs! They are expensive so try and borrow a set to confirm the fault before you buy a new set!!!

May not be the same problem but the map sensor pipe fell off on mine and it wouldn't rev above about 5k - felt like it was hitting the rev limit. Pipe is near brake servo (ish).
