Cool well that answers my question in a previous post 2dfx Glad to hear you got her running good again, i figured it was somthing simple> funny cause after you had problems my engine started missing real bad, come to find out it just needed new plugs > i didn't have a bit of trouble installing them though, I just let my mechanic climb on top of my engine and change them while i installed his new dash speakers in his Camaro! We trade out Mechanical labor for stereo equipment > works for me
