I am having slight jerking problem during take off.

Its common during take offs from a stop but cruise speeds doesn't do it at all.

I have no clue what can be the cause but I tired another ecu and that hasn't fixed it.

This is 89 civic si. No Check engine lights at all. I changed the dizzy, spark plugs, wires. Still hasn't been fixed.

Anyone have any ideas..I think one of the sensors are messed up which I am not 100% sure. Anybody with any sights please speak up thanks

 

You say you changed the Distributor; maybe it's off a couple of degrees?

 

ohh nahh the timing is correct I used a gun and set it proper then I went to smog they check it was fine also. thanks!

 

torque steer y0!

 

Fuel issue? Filter? Injectors. Sounds like something like that.

 

yea I was thinking injectors also, but I have changed the filter before. I have no idle problems car runs perfect passed smog in ca etc. Expect it jerks during take off from a stop..

fuel injectors are expensive I don't want to keep replacing parts..I already spent about 400 in parts new dizzy,cables,relay etc..

 

torque steer

 

y0!

 

You already said that. He didn't say he was launching it, and last i checked torque steer doesn't make the car jerk.

 

When I had shitty loose balljoints on my old DX the torque steer sure as **** would make it jerk.

Maybe he needs to describe what exactly his problem is a bit better.

 

Are you talking about it jerking to one side? I think if that was the case he wouldn't be replacing his ignition system.

 

try adjusting your idle with the idle scew first. bring it up a few hundred rpms.

second, how are your mounts?

 

Could the clutch be slipping?

 

what do you mean when you say jerking though like just feels like your dumpin the clutch to quick?

 

u must have never been in a fwd car that has power than...cuz a k20 eg has mad torque steer y0!



op try ur ball joints/steering rack...something seems loose and doesnt seem to be mechanical (engine wise)

 

maybe it has something to do with engine mounts.

 

the clutch is brand new so is pressure plate. jerking meaning slowly take off it will jerk like it doesn't want to go more like car is hesitant when taking off low rpm. mounts are all good I replaced them last time I did the clutch.

 

yea I will try that.

 

mind starts jerking at a high rpm like if i was to go tap the gas on and off on and off on and off similar to that

 

maybe ur throttle cable is getting caught up

 

how would it be getting caught up like it being to loose are something and i was also thinking my car idles a lil high but not sure could be my cable

 

for smells and ef, do check both your cables and the idel screw.

but ef, im leaning more towards a bad engine mount, have you checked them lately?

 

thanks man goin to go find my idle screw i was thinkin maybe vacume leaks how do u really check that can u fill are u just use soap and water r n e thing

 

ill say fuel filter or injectors maybe dirty gas tank clog up fuel lines somewhere. use fuel cleaner i guess.

 

yup thats it
