Can I put them on my 95 GT, the light keeps comming on with my full exhaust system, and what could cause my idle to keep being at like 2000 rpm except a vacuum leak, I can't find the problem.

 

yeah do a search my friend had found some real cheap , someone made them at home , cost like 20 for both not 50 or 60 like most charge , i have also run across some places that show you how to make them there not very hard to do .
