well i reinstalled the ignition control module(first time i didn't use the good dieelectric grease) so then is started right up and ran for like 20 minutes and i even took it around like 20 blocks and got back shut it down and it started the first time i tried then it wouldn't anymore. now when i turn the key it is chugging like it really wants to start and after i let off the key it still chugs for a second and it wasn't doing that before. i think that perhaps i got two problems at once. fixed the first part but what could be the other problem.
