AKIRA Posted November 12, 2004 Share Posted November 12, 2004 the engine keeps cutting out when it is under stress, like full throttle or going up hills, this makes it very hard to drive, because it can only go slow, or it would cut out.

idosubaru Posted November 12, 2004 Share Posted November 12, 2004 check your air filter. how is the ignition system? coil, plugs, wires, cap rotor? fuel filter (i doubt it, but easy to replace) anytime i'm faced with a problem i like to replace all this stuff to start, because it's cheap, keeps the car running good and eliminates them from the possibility. except the wires, i have magnecor wires that will never need replacing. everything else, i replace often. i don't know jack about brats...i guess it's carbed but if it is not - how are your fuel injectors, fuel pump? see any fuel leaking around the fuel injector seals? if it's carbed i can't help you much on fuel supply.

Sweet82 Posted November 12, 2004 Share Posted November 12, 2004 I second the motion on the Cap, wires, rotor. I'd give it a good basic tune and see if that doesn't clear it up? I had the same thing many years ago and it turned out to be a wire? A basic tune finally took care of it for me. Good luck Glenn 82 SubaruHummer 01 Forester Quote Link to comment Share on other sites More sharing options...
AKIRA Posted November 12, 2004 Author Share Posted November 12, 2004 it goes like this: at full or near full throttle, it starts cutting out. today on the way to the college I had to drop from 70 to 55 to go up a hill (any more gas and it would have cut out) - you know how you have to floor it for hills there is a problem, I don't know what year the engine is from (it was replaced before I got it), and also what timing is specific for the engine. I got a new cap and rotor for it, but it didn't fit, also we changed the timeing and it made no difference, still does it. cap, rotor, tune up. got it, I'll figure out what its from oh and also, could the sceondary barrel on the carb somehow be causing this? the vac line to the secondary was cut and plugged, along with 4 others. maybe he did it for a reason. P.S. I removed the vac valve to the sec. and did the 1/3 throttle carb mod. Quote Link to comment Share on other sites More sharing options...
AKIRA Posted November 13, 2004 Author Share Posted November 13, 2004 put on new cap & rotor, it made no difference Quote Link to comment Share on other sites More sharing options...
stngllhm Posted November 13, 2004 Share Posted November 13, 2004 is your choke sticking closed? i had a problem like this on my 84 wagon and it was the choke Quote Link to comment Share on other sites More sharing options...
Qman Posted November 13, 2004 Share Posted November 13, 2004 FUEL FILTERS!! Replace both of them and the problem should go away. One is in the engine compartment and the other is under the Brat near the tank on the drivers side I believe. Quote Link to comment Share on other sites More sharing options...
AKIRA Posted November 13, 2004 Author Share Posted November 13, 2004 the choke is working alright, I am going to go to advance auto in about a half hour, I'll get fuel filters too. Quote Link to comment Share on other sites More sharing options...
AKIRA Posted November 14, 2004 Author Share Posted November 14, 2004 I replaced the one in the engine bay, but not the one under the car, do you think that the filters are really the cause of this, how? not high engough fuel pressure? I have done so far: adjusted timing adjusted valves replaced cap, rotor, wires fixed exhaust leak the carb secondary mod Quote Link to comment Share on other sites More sharing options...
AKIRA Posted November 14, 2004 Author Share Posted November 14, 2004 after I posted I put the other filter on and took it for a drive: IT DIDN'T DO IT!!!!! YES!!!! sorry for doubting you qman. now to see if it was just a fluke and test it on the highway tomorrow Quote Link to comment Share on other sites More sharing options...
