ok i got the 3k bucking problem..... so far the reasons i have found are clogged screen on fuel pump, AFM, leading igniter, injector wiring, and TPS......i recently adjusted my tps..so im ruling that.... but the odd thing is that it started after driving for maybe a mile to my gparents after a hard turn i just thought it was my gas being low when it sputtered and went on down the road and pulled in turned her off and stayed for 30 mins got back in left and floored it and at 3k it bucked...just last night it was just fine? so im thinking maybe my igniter...so how do i test it??? and what are other common things i didnt get???? thx

Well if the engine is running and the time circuits are on, there is only one thing left to check:

Jozay721

its not reaaly accurate but juts idle the engine and pull one of the ignition coil wires, and try not to get zapped, thats one way with out the test hayness has to offer.

cdrad51 i already checked the flux capacitor! its an 85 gsl-se by the way..what about just switching the igniters? will that tell me nething??

cdrad51

lol ok if the flux capacitor is fluxing, you can test the ignitors by seeing if you're getting spark at the leading and trailing plugs. If you got spark, you got working ignitors. Got a timing light? easiest way to find out.

Ignitor are usually working, or dead. If it's intermittent, it maybe ignition wiring. Check the connections on the dizzy and at the coils.

With your description, my 1st check would be fuel related components, then the bac and the linkages for the throttle plates, providing the tps is dead on.

i dont mean to question u throchoid, but my tailing igniter was going off and on till it went completely dead, i could tell this because of the tach, the tach is hooked up to the yg wire wich is on the trailing igniter and the trailing coil, the tach was bouncing up and down, then went to 0 then to correct rpm till one day it died, problem solved though i got a new igniter, im an idiot though, i figured out how to fix my old one and dint return thenew one, o well.

The off and on charge through the ignitor may have killed it from overheating. I'ts my understanding that they work or don't. Don't worry about questioning me, I'm not always right and don't know everything, working on it though. lol

Jozay721

yeah but ur smart and i dont want u to be mad at me because i am saying something different.lol, yeah id say ur pretty close.

rolfs_7

well it seems like the leading is getting spark, i accidently disconected it when i was trying to do somthing and it arched sparks all over and hurried 2 get it back on...so 2marrow im gonna do my tps and look at my fuel pump and filter

You are lucky it didn't shock the **** out of you.

rolfs_7

haha yeah we used 2 do that with my friends old go cart with the plug wire....if u touched the top of the engine where the plug went in i fucked shocked u bad lol so we would tell people 2 feel how warm it was good times...

I say change the fuel filter and clean the screen then try running the car.
Also it would not hurt to buy some Seafoam at your local Autozone or Advance Auto and pour about half of the bottle in the gas and the rest in the oil.

GavinJuice

whats the reasoning behind adding to the oil with the symptoms he listed? i understand fuel...

rolfs_7

i put some mmo in her a while back..seafoam does wonders...i just changed the oil so i probly wont put any in the oil. thanks for all the advice ill post back in about 9hours when i get all that done

Seafoam does wonders in the fuel and in the oil. It helps clean out the fuel system and carbon off the motor.

ok well i took my fuel pump off and didnt find and screen, the fuel filter looks fresh and i had some papers saying it had been changed its a napa gold filter. but i got a problem now i put the pump back on and it leaks outta the back of that valve looking thing on the side the fuel is pumped out...wtf its got a tiny hole on the top where is leaking from can i just put a screw in it and plug it or do i need a new one????????

rolfs_7

i need help asap its dead in my drive way...

I had the same problem a little while ago, have you added anything other than gas in your tank recently? I had put some carb cleaner in mine with a half tank of gas in there and what happened was the gas got so thick the carb couldn't take it. Thus, the bucking and dying. If you did add something in your tank, I suggest emptying it out, buy a new fuel filter, put new gas in the tank and then add slow amounts of the mixed gas in every now and then, that should remedy the problem.

rolfs_7

no i havent added anything in a long time...but im still having the problem with the fuel pump part
