I was clearing a code 224 and diagnosed it to the Ignition Control Module(ICU). Whilst replacing I noticed there were only three bolts tapped into the manifold mount. I'm missing the fourth bolt hole in upper left corner of the ICU. These modules do not work with only two bolts, you must have all three bolted down...ground issue I'm sure. The 224 fault code is all but gone after I replaced the ICU a few days ago. It's breifely reared its ugly head on two brief occasions opposed to constant check engine light memory code.
Does it only have three bolts by design? Now I wonder, is the fourth missing bolt a contributing factor to the ICU failure and the code 224?
What say ye? Oh, by the way first post, love the board.
