Hi all- brand new to board, and relatively new to being a happy 'baru owner. (almost a year now). the deets: '84 GL wagon, 4x4, replacement motor from Japan (EA81 or 82?- will double check tonight)

 

So i've been surfing and searching the old posts here and other places, and as i suspected, i'm not the only one afflicted by a hesitation and bucking under power. i figured initially it was a fuel supply issue, as it only happened uphill the first few times, and felt like an empty gas tank-bucking. now that it seems to have returned after a brief absence (warm weather turning colder?) and i can make it do the haunted hesitation going up or down hill, just as long as i get the rpm far enough up. downhill/flat seems to be at 4k or higher, and going uphill, just under 3k it'll start. this is usually in 3rd or 4th, but i can force it in second if i try hard enough... don't like doing that though. also, if i control the buck by letting off the gas it won't get worse really, but if i push it harder to really starve the motor, it worsens much more quickly.

 

i'm hoping experienced subie owners may know the symptoms i'm describing now, but i've seen many a thread with these symptoms from different angles, including the spark (coil, module). so while i'm now thinking vaccuum advance may not be working properly, i wanted to get some more experienced opinions on this. is it a fuel supply/carb issue? or is spark the culprit? if the latter, would you guys think it was more coil or more disty?

 

happy halloween to subies everywhere!

Plugged accelerator pump or jets. Clean the intake also.Possibly Egr valve.

i tried a bottle of techron for the intake- will try some carb cleaner tonight, and see if i can find the egr for future reference. you think the spritz is enough, or do they usually need dismantling and soaking?
