i did some searches but could not find what im looking for.
i just noticed this the other day.
at a stop light or when ever i have to brake for a long period of time
the car starts jerking. the RPMs drop about 100rpm and then the car
goes back to normal. but now this happens continuously at stop light.
even when i let go of the brake to let the car roll forward, the car still jerks
only until i press the gas the car is normal. and then when i am braking to
a stop it also jerks.
the jerking is not noticable outside, but inside the car you can definitly feel it.
the car drives fine with no jerking, this only happens at a stop...
this has happened in the past but not continuously like it does now.
before i would only notice it once in a while at a stop.
and this happens only when the car is warmed up.
could this just be a tune up thing? my 93 has about 129K on it,
but i think the last time it was tuned up was around 75K...

what are you guys thinking it could be?
quit giving me more questions, i want answers!
i want to figure this out quick because it is seriously bothering me.
i dont feel like driving the car anymore until i solve this problem...
Pull the dipstick for the tranny and describe the fluid condition...
It should be a translucent red when fresh. It wil get darker as more miles accumulate. Smell it...if it is burnt...that is not good. Many people ignore tranny service until it starts acting up but it requires regular drain intervals every 30K. You can go longer, but it's just not a very conscious way of car care.
Good thing is that the 1UZ trannies are near bullet proof so if it is the fluid, a drain will make it happy again.
If the tranny fluid is good then there is probably something else causing the problem. An overfilled tranny exhibits problems but this is immediate onset, not delayed. Ted from Dynamic told me that you will also get a check engine light in this case.
Possibly an ignition wire or spark plug issue? Might have to pull the plugs to inspect.
Besides checking the fluid itself, also should check the tranny filter and the tranny pan. True, many people do drain and fills and even flushes of their ATF, but particles can build up regardless with that many miles on the vehicle. If those particles get back into the system since the magnets in the pan or the filter itself is saturated, there can be issues.
