mine is probably bad. I've had the hesitation these cars are known for thought i could get by with changing plug wires to ovc. Well i did have to burnt stock wires but ovc made no difference So my car is really pokey now does a bad opti make that much of a difference i mean it feels slower than before any of my mods any ideas?

 

It can really mess with the ignition. You should probably just go ahead and change it out with that kind of mileage anyway.

 

yes it can make a huge difference.
