hey there guys i bought a 95 wrx wagon import with blown heads and after getting this fixed at great cost the car hasnt run right since i got it back,Here's the problem,the car looses power in a chugging motion,backfires like a crazy gun man.ive had a number of people look at the car and they cant narrow it down,its also not coming up with any fault codes.just to let u know the car wasnt running like this before i had the heads done,so any advice before i shead out loads more money trying to get it sorted.

 

sure the head gaskets were correct thickness as this could cause incorrect compression think if there too thick it can lower compression? someone please advise if this is wrong. start a process of illimination .
turbo ok
fuel system- fuel pump, fuel filter, injecters
ign.system- plugs, leads, coil,
or maybe the timming wasnt put back right , or might just needs a good tune up. personally think it might be down to the timming it sounds the most obvious hope this has helped know it sounds alot but if you get the timming checked then if thats ok get a compression test done if the two most likely things are ok then start checking the rest good luck buddy

 

yeh im sure its the timming or compression if the car wasnt doing it before
id get it back to the garage or person and get them to sort it mate
anyone else any ideas please

 

its been back to the garage every weekend since he did the gaskets what was about 3 months ago and he cant seem to get down to the problem he checked the timing,but every time i get it back it seems to be getting worse,i was thinking about taking it to (well lane turbo centre) i will let u know the outcome,but if anyone else has anymore ideas or had simlar problems feel free to let forth your wizdom. ;o)
Thanks
stu

 

any chance when they took the engine out that they havent put the inlet manifold back properlyand its taking air ? ive had a couple of people tell me this could cause the symptoms im having

 

Has the garage compression tested it and told you what the results were?

 

hey up guys i took it to a guy at ART who plays with fast cars everyday close to where i live and it turn's out it was the actuator ;o( and a spark issue was causing the backfiring.so here goes another uprated part for my pet subaru.
