My car would not start after new Air Flow Meter Tower replaced. Well I made adjustments about 1/8 turns clock-wise until the car finally started, then turned screw in tower CW until engine started to run rough, then back until it started running rough in the CCW direction, then found a happy medium in between. Engine now starts and runs ok, revs smooth with good response.

The engine idle ran a little rough until the Idle Control Valve came on, and this was only after the engine was warmed up a little. (have a little bulb connected to the two wires so I could see when it came on) When it did come on the engine idled much smoother, and dropped from 1100rpms to about 750. Does someone know why the Idle Control Valve would take so long to come on?

I notice one other thing that does not seem right. The fuel "Economy" gauge's needle, at idle, is not near the far left (black area) but instead is a little into the beginning of the red bar, just pass center. Anybody have a idea what is causing this, and how to fix it?
