I recently purchased my 95 mustang gt convertible with 68000 and am starting to notice that it takes 5 to 30 seconds to start that in itself is annoying, no sometimes when i drive on the freeway my check engine light comes on, then goes off. i put on a cold air intake, new cap, rotor plugs and wires. I tried cleaning the IAC with butterfly valve cleaner and that did not seam to help. also i recently had to change my radiator. my little toy is starting to get more involved and is getting frustrating any help or suggestions would be greatly apprecieated...
