the IAC will cause the engine to run rough at idle. The TPS could cause the engine to stumble, use an ohm meter to check to see if there are any dead spots. Did this problem just start or has it been around for a while? If it has been around since the engine mods I would look to see if you have proper fuel pressure for WOT running.
