the kids are all right here. vacuum, vacuum, vacuum. system gets old and leaky and messed up and makes the CIS-E go nuts. so with the ignition gone nuts, people start to look to the ignition for the solution. but it ain't the first place to look, but maybe the last place to look.
slight vacuum problems can cause huge problems for CIS-E. It's a nice system, when it works, but isn't everything nice when it works? On 11/28/06, LarryT <[EMAIL PROTECTED]> wrote:

Often people jump to the fuel delivery system when the ignition system is at fault.
