i have a 94 wrx seems worse when damp the car tries to die and seems to missfire and hesitant? when its a dry day seems a lot better also when warm the engine pops back when changing gear and also when releasing throttle to slow down have been told flames shoot out back on occasions have not fault codes on ecu running optimax fuel any ideas

nice guy

Flames and popping back are quite normal if you have a straight through/performance exhaust mate.

Misfires on damp days, poss coil packs.

What air filter you got?

Is it ok when the ngine has warmed up?

It could be (in no order) maf, lamda, coil packs, leads, plugs.

So would be worth getting it diagnosed before you spend the money...

When i had a HKS pod filter on, she was a pig to drive on a damp day, below half throttle she would die, so you put youre foot down a bit more...a bit more.... a bit more....aaarrrggghhh BRAKE! Used to keep me on my toes driving to work.

Eventually i tried the oe airbox on which i got with the car.....hey presto. runs like a swiss watch come rain or shine.

I dont like foam filters....they dont have good filtration capacity anyway.
