cam and surging and loping

my cam also lopes around like a bitch, if i start it when the car is cold it idles at 1000 and it runs fine but if i try to drive it, it seems like it is lagging or surging. if the car is hot or warm on start up the idle lopes around alot and have to rev it to keep it alive. but once it warms up it's fine, how do i fix that? would a dyno tune cure it? thanks sorry for hijacking ur thread but i was just goin to start one and noticed ur having the same problem.

ok i tihnk my computer crapped out. when i got my car done at that shop he was telling me the check engine light came on and when he scanned the computer for the code it came up "no code" he was telling me that computer might be bad. so yesterday i was driving and and i heard a beeping coming from where the computer is located. shortly after i tach stopped working then the speedo then the other gauges. i was trying to make it home and the car started to run like crap and had to rev it to keep it goin the my radar detector went on nad off and the clock stopped working. then the car just died. and when i went to go start it all i got was clicks. then i tried jumping the car and all i got was clicks. nad i have power in the car, has my computer crapped out? how much is an aftermarket computer? thanks -Jeff
