My '96 Cobra seems to be having some Idle air control problems. While looking for a new one, I've found that the one on my car does NOT appear to be the one prescribed for a '96 model. The one that is listed has a large nipple for some type of hose attachment. The one on my car is like the one for '97 up without the nipple. Was the design changed during the model year run or has mine been modified / changed? BTW, they are not easy to find at parts houses and I hate to pay dealer prices. Hopefully O'Reilly can order it.
