Remember -- I have NO idea what I'm talking about. I've owned my 1988 Subaru for gong on 4 months now and never owned any vehicle so complicated before in my life. It's all gizmos and gadgets ....

looked at it very quickly tonight, heard a ticking around the acell coil, all wires good ,ngk plugs, new cap, rotor, ??
Boy, I don't know even more about this.
In electronics, a ticking or buzz or whistle (a really fast 'ticking') is often a capacitor that is just starting to break down. The voltage builds up, and before it reaches its rated capacity, the electrons escape through a low-resistance flaw. Each time it makes an audible pop. Once you get 440 of those per second you've got a concert "A" musical note (grin).
Any coil can do that, if there's a little flaw in the wire insulation so instead of going end to end the electricity short-circuits. So can any place that is supposed to be properly insulated.
Aside -- if you were talking about digging into the guts of a monitor or TV, I'd be warning you how to avoid killing yourself by discharging the high voltage capacitor (you take a long wooden stick and a piece of chain, attach one end of the chain to a good grounded pipe or wire, then let the other end of the chain drape over all the exposed wires on the (unplugged) monitor til it goes snap-crackle-pop convincingly) -- high-voltage capacitors can hold a killer charge for literally weeks after the thing's been unplugged.
It's different with car computers, less than five volts (much less than you can see or feel) of misplaced electrical discharge can screw them up.
I guess with new cars that have computers in them you ought to ask good advice (not mine) about protecting the chips, as well as yourself, before messing with the electrical system.

Located on the front of the throttle body..
(the gizmo that the thottle cable connects to)
Has a wire and a rubber hose connected to it
There is a picture and a cleaning proceedure
in a previous post.........
Good luck, hope you find the problem is
as simple as this "shoud be" maintance item

the ecu kept pulling maf codes intermittently, as wiggling wires caused inconsistent troubleshooting
jim, didnt you clean the aic, or have me clean it? i remember cleaning one there unless it was the one on the sedan. maybe when the motor(in the dl) was still in the blue wagon i cant remember.
