Subject:      1987 High Idle - $3.13 Fix

Vanagonauts,

Recently I related the story of my 87 Syncro suddenly developing a +4,400 RPM idle. I traced this to the Idle Control Module located forward of the right/rear taillight. The dealer said list was $208. I called several wreckers and was quoted from $80 to $20 for this item. I bought the $20 one and it arrived yesterday.

Meanwhile I was pursuing repairing the bad module. Inside the module I discovered two components that were suspect. The first one, a voltage stabilizer transistor was definitely fried. I found (from my 88 Vanagon module) a company logo: SGS in tall narrow letters pushed up against eachother & other numbers were BD 438 and 9 741. I found that an ECG or NTE 185 was a replacement component for it. The other component was a rectifier diode that had some signs of being overheated but was not overtly fried as the other component had been. The diode had the numbers GP15G-7001 and GI 8641. I thingk the GI is for General Instruments. Well, found that it could be replaced with an NTE 125 or ECG 125.

Yesterday, I installed the two new components and the bottom line is that after poping the module back in, my van idles normally again! :)

Cost? NTE185: $2.25 NTE125: $.88

Total: $3.13 + tax

Compared to dealer list, I saved about $205. - that's 98.5% less!! :) :) :) So now I've gone from needing a new module to having a spare for future use. :)
