hi, i own a impreza wrx turbo bugeye 2002

only modification are a blow off valve and a pro drive back box

i have been having this problem for some time now with engine management light coming on reading error codes of cylinder 1,2,3,4 misfire. the car runs rough and idle is low and sometimes cuts out when at junctions. loss in power in low mid and high range. read numerous post on here and other forums and from what i can gather its either ignition coils need replacing or something much more ominous the engine compression has gone....

i have tried replacing spark plugs for new ones, changing coils around( when the error read it was just 2 at the time), cleaning maf sensor

before i go ahead and buy a set of 4 ignition coils (eBay £149) and replacing them can any one tell me if its really worth doing or am i wasting my time. ie compression gone= new engine or big bill to fix

i have noticed one other problem of a leak from the gasket at the turbo to the down pipe, surely this has nothing to do with it.

thanks for reading and any help would be appreciated

so i went and got a compression test done, all the 4 are reading between 140-150psi which is good rite? noticed the spark plugs i had changed where pretty dry and clean? tested each coil pack and all 4 were firing. changed the fuel filter as well while a was on and still no change in performance and eml reading error codes of cylinder 1,2,3,4 misfire.....

any ideas? maybe a fueling issue?

Faulty MAF, split intake pipe so theres unmetered air entering the engine, fuel pump on its way out, water temp sensor or timing belt jumped teeth. Have the AFR's checked to see if its a fuel mixture issue or ignition issue causing the missfires

don't waste money on coilpacks, it isn't that, most likely your BOV is leaking badly, is it an ebay effort ? lol

well after a 4 months of trying to find this problem its finally sorted! turned out to be a collapsed/blocked cat haha. replaced the turbo bk and the up pipe b4 the turbo to a 3" de-cat. while i was on i replaced the turbo as well and wat a difference it has made to the car. definatley keeping it now it makes my face do this Laughing  

thanks for all the help, next question is will the car need a remap now? and what is safe boost to run on a standard turbo?

cheers

Mate if you have removed the cat and changed size of exhaust and change turbo you going need a map mate so be careful
