hey everyone, here is my issue, i have a 1990 thunderbird sc. i just installed a brand new short block in. when i first had it running it ran a little rough but thats because of an aftermarket cam and it ran just fine. later on i took it to get painted, when it came back it didnt run very well anymore. so i ran an injector ballance test, compression, noid light test, and spark test and everything worked just fine and dandy, so now im kinda thinkin.....~~~ if anyone has a clue what i might find wrong please let me know thanks!
