I replaced the Opti and i'm still having problems. When I accelerate hard it's like riding a Bucking Bronco, Soon as I let off the gas all is better, nail it again and yee haw !! I need to bring closure to this issue....... Thanks

 

yep, i had that problem! it was the coil on my car. when my second car started running bad, i put on a coil first. for 40 bucks and ten minutes worth of work, i found it's a good spot to check first!!

 

I had the same problem and the coil and coil wire were the culprits. Check for white powery residue on the coil contact and in the coil wire. Also, your o2s might be on the way out...can get that checked by scanning your computer at autozone.

good luck.
