Alright i had a slight bump with shifting then i replaced my bad injecter. Returned the power back from 500-3400 rpms. It shifts smooth the first few minutes i drive it but then it bumps a little bit with shifting. its only after i drive it for 5-10 minutes. I know my cv shaft boots are completely ripped and i have a very small exhaust leak near the front of the engine. would that cause anything like this. im getting frustrated serverly cause I havent had her running smooth in awhile.

 

does this happen while applying gas, or letting off of your gas pedal???? if so, check your lower control arm bushings, or ball joints

 

both. when the gas is applied and it shifts it is less noticable. when i let off the gas and it shifts its more noticable

 

possible bad motor mounts?

 

i have no clue what it is. wish i could have someone take a look at it for me :-( its just weird how it shifts real smooth when i first drive it but when it warms up it bumps a little.

 

I know exactly what your talking about my 89 maxima does the same thing I hope theres a solution!

 

the solution is to have a 5 speed transmission.

 

1. get a phone book
2. open it
3. look under Automotive
4. find a shop, fork over money

 

haha gunna sound mad funny but i noticed my coolent was mad low i forgot that when i took off the manifold for my injecters that the tubing for coolent leaked. i refilled that and it helped a little bit. not quite as much bump but still a little.
