I know how your feelin, reaching back to unsnap those heater hoses from the old core was a nitemare. I still have scarred knuckles and that was a few months ago. I just bought one of those OBDII hand held scanners from harbor freight but have yet to use it. I thought if I had no light on the dash that it wouldnt show anything but I'll give it a try anyway. The cops I got were the accel copies and at 130 for all 8 off Ebay,thought I'd save a buck or two......... I just got back from a 16hr trip, to and from Tennessee and she only missed every now and then but it was enough to burn up some gas thats for sure. So tomorrow its coils, plugs and I'll change the belt because its definitely seen better days. Only hope I dont have any of those plug problems everyone keeps talking about. I'll do the seafoam and let'm soak a few hours. Thanks again for all the info, I appreciate it
