Yes, IPC problem resolved. I purchased a non-working IPC from Jim Finn and sent it to Cluster Fix for repair. They did an excellent and fast job, even polishing the lens to like-new appearance. When I received the repaired cluster, I swapped it with the defective cluster, and voila, the IPC now lights up every time. I paid a bit extra for the Cluster Fix 3 year extended warranty. I highly recommend Cluster Fix. Based on what Reatta experts told me, 90% of cluster issues are the cluster itself. I had no desire to tackle the innards of that cluster myself...a job best left to the pros who have "seen it all" and know exactly what to do to fix the problems for reliable service.

Sounds like a real keeper. I like the body style.

Well, that’s a series one L27 engine, so some of the potential vacuum leaks aren’t an issue, like the pcv for example. Gradual loss of power would seem to indicate a buildup or steady decrease of something over time. Does it run differently with the power loss, such as rougher running like losing one or more cylinders, or just like it is laboring more? You may need to install a long hose on a fuel pressure gauge so you can see it under load. Are you familiar with the built in diagnostics? You can monitor several engine parameters while underway. I saw the mention of rerouting rear plug wires making some improvement which is curious.

I would think that it will but maybe check with something like Rock Auto to see if that part number crosses to earlier engines. My memory says that compatible ICM’s were used right until the end of the 3800 engines.

The other thing to consider is that you have very low miles and may have sediment in the tank that is stirred up and clogs the fuel system. Car is then turned off sediment settles down again and the process starts over again.
