Sputters ?

[LeDevil]

When I drive my car and shift around 3500 rpm it will sputter and bog down then if I take my foot off the accelerator and SLAM! it on the pedal it will kinda stop. This only happens in 3 to 5 th gear around 3500 rpm after that it will do it aswell. Any Ideas as of what it could be I put a new cap and rotor and plugs in today thinking that might help but it didnt. Any help is greatly appreciated

Thanks LeDevil

 

EDIT: Yes 4th does it aswell I forgot to mention it does it mostly when I put the car under a little bit of stress like climbing the hill to my house. I have to keep it in 2nd just to be able to climb the hill and not have it cut out on me and die.

Thanks LeDevil

fuel filter? usually those has a lot to do with bogging issues. however my car does the same when i floor it - i just dont think the car has enough power at that rpm to jump a few rotations faster so it does the opposite. kinda like its being flooded.

 

are you sure it is specific to just 3 and 5 gear? i'd think that 4th gear would be in on the boggin action too since it is a higher gear as well.

Any ideas?

Well, ifin it's a carbed engine, I would guess a weak accelerator pump in the carby. Just sounds like it could be that.

 

Other than that, would check for a vaccum leak somewhere, that would come in on the high rpm side. Not really all to familuar with how Subaru did/does vaccum sorcing, but learning.
