Hi set off to work today everything ok, after2 miles i get a splutter and the engine starts to die off , managed to keep it going but no power and it poped and banged , had to feather the throttle to keep it running , when i stop it cuts out but starts back up ok , turned round and headed home still spluttering along , then the check engine light came on as i got home, AA has been out and says his computer carnt read my car so has no idea, the car starts fine but runs rough and smells of fuel from the exhaust, any ideas wot it could be , when i was on the way back i managed to get it past the splutter and it pull well but as soon as the revs dropped it limped along,

Hav eyou checked the pipes to the intercooler etc. if one of them comes off, it dies when the revs get to around 3k rpm., but starts ok....

else i guess maybe the maf?

Do a search for saxonfield on here as it tells you how to check for error codes

had a same problem lately as describe by octane but the CE light went off by itself and power was restore. anyone has any idea wat is happening? had check before the code and is reading maf but it comes once in a while only

Sc0oby

also forgot top mention exhaust smell bad and fuel economy is not as normal before. Could this be a hint that the maf is on its way out?

i would expect so as the as i think the ecu alters itself to run with the bad sensor (don't quote me on that though).
Can you go to a friendly garage to borrow a new maf and see it that makes any difference.

myblackwrx: sorry scoobies are very limited in manila philippines. there are only a few sti gc8 running. i am also an importer but most of the vehicle i acquire from japan is v5-8. Mine is a V3 so spare parts is hard to find.

also car is running fine as well. I was also thinking this could be related to loose maf connection that is causing the CE light to come on when running on rough surface. Asian road has very bad road condition.

Sorry didn't realise you were in the Philippines easiest thing to do i suppose is to try and repair the maf connections.
NeweraParts > Home are in Japan (english speaking)and say they can supply nearly everything from the simple spares to the major mods might be worth trying them.

myblackwrx: i am also sometimes experiencing hard starting it seems to be running very rich

I think you may need to replace the maf give that a go and see if it solves your problem

myblackwrx: Would i be able to use my old 97 wrx Gt AFM on the sti v3? as a temporary testing as i would have to order it new and it would take some time to bring in. The AFM is identical except for the larger diameter on the sti v3
