So somedays my gsr jerks for a quick sec while driving. Only does it sometimes bc some times from point a to b its fine. but there are times motor just starts jerking and boggin for a quick sec, but does it repeatly.

Usually does it from shifting from gears feels like the clutch doesnt grab but then jerks and then drives normal. I had my clutch changed like a year ago. On the highways cruising liek 65mph motor starts to jerk repeatly then stops and sometimes it will do it again and sometimes it will drive normal.

Someone help!!!!!!!

louuu

bad motor mount?!

sick_dc2

naw i replace the rear one. and side ones.

its more like the motor bogs and the when i only acclearte like 5-15% and never happens at half throttle tle or full throttle. it hesitates for a quick sec and then goes. sometimes just once and sometimes few times. almost like stallin out but my speedo stays normal.

sounds like spark. whens the last time you gave it a tune up? new cap, rotor, plugs and wires can do wonders
also check your grounds, the motor needs to be grounded, maybe one fell off

sick_dc2

ahhh good idea! will change that tommorw! hopefully it works!!!

teg_racer

let me know

yep sounds like a cap and rotor problem too me, had the same problem in my hatch, changed the cap rotor and plugs, ran perfect after that...

Yeah cap/rotor should do the trick, fuel build up in a cylinder from a detonation that wasnt right gives a jump or "Jerk" when that cylinder fires again. Bog is from lack of spark, so get some good wires too for the hell of it

sick_dc2

okay so was checkin my spark plug wires and the cylinder 4 one is hardly given any spark!!! change my spark plug wires and still does it. and i took off my cap/rotor and ***** looks pretty cleann??!?!?! should i still change it? still stumpppedd alsso now my rpm's are jumping crazy but motor not revning, jsut the tach. bad vss? would that make my car jump?

It only jumps/jerks when im cruising and hardly on the gas maybe like 5% and jerks then i step on the gas more it will finally stop untill i come back with 5% of gas

A jumping tach is usually a sign of the ignitor wearing out I want to say, how old is your distributor?

sick_dc2

no clue, i bought the car like maybe 3 years now? but gonna go parts store in the morning and hopefully it will fix the problem
