Ok, i have a 99 I30t w/ an auto tranny. My problem is that a couple times w/ in the last week during stop and go(traffic) my car seems to studder or lurch until it goes 1 to 1 or above about 10mph. Once above that the car drives fine. when i try to accelerate though, the rpms go up to about 1000 then drop suddenly to about 250-300. Sometimes they will go back up enough to make the car move and sometimes the car will cut off. Whats going on? Thanks

 

Sounds like a problem with coilpacks or IACV.

 

should i have it looked at? i mean could i keep going and by changing the trans fluid might help? thanks

 

It's not your tranny, it's your engine thats not running right.
