Hey all,
my main reason for posting this was to say - if you havent looked at your 2.5L H4 recently, pop that hood and make sure that all the intake silencers are still fully attached. I was hunting down a P0303 and found that the big one was resting on the fender...with a few mm gap between it and the flange where it is supposed to connect to the intake pipe.
Still has the P0303, I'm gonna replace the coilpack, plugs and wires becuase its time to do it anyway- hopefully that'll get rid of that.
None of the threads about intake silencers talk about the 'extractor' effect and the resonant volume helping the engine breathe better (If we think that suby intended such - has anyone dyno'd a 2.5l with the silencers on and off ?
so I'm thinking - if (one of) my intake silencers was disconnected and open to the engine bay - shouldnt that hurt power more than just from the hot air ?
2001 OBW, 2.5l 4EAT, 100k miles - Normally hauls a wife and 2 kids with 200lbs of toys/food/strollers in the back - She gets 19-20mpg in mixed city/highway driving and a light foot (got to be careful with the kids y'know =) I was thinking that this mileage was slightly worse than average but maybe I just found the culprit =)
