The idle on my car dips down about 200 rpms when I first give it gas, which makes take offs kinda jerky. Any one know what would cause this? The cars a '97 GT 5 speed manual tranny. (2nd problem w/ my 'new' car if anyone read my other post)

Sounds like your car's running rich. How do the plugs look?

I took the car to the car I bought it from and he said that its a bad plug wire, does that make sense?

I'm going to drop the car off to him next week so he can fix a few problems w/ it (in reference to my other post about the popping noise, he said the lower control arm bushing needs changing)

Find the leak and close it. But, yes, it could be a bad plug as well - could be a number of things to be quite honest. A clogged fuel filter comes to mind as well.
