20 mins ago im in the wendys drive thru n im waitin for my change and i feel the car kicking and while its kicking my rpm goes from 650-about 750..up n down..i tried putting it in neutral to see if it would happen but it didnt..can i be misfiring or something.??

the car is a 99 auto loaded..cali spec

 

Yes it sounds like its misfiring. Since 99's are known for bad coil packs, I would check those out first. Also when is the last time you had a tuneup.

 

actually just bought the car..havent done it yet..how do i check the coil packs.?
thanks

 

Check the stickies at the top of the threads.

 

alright thanks

 

just replace your coil packs with some used ones

99 coils are complete garbage

 

Definitely replace your coilpacks. I had the same exact symptoms, all the way down to the "kick only when in drive". 6 coils later, they're gone. I have a Calispec 99 BTW.
