I read that 86 and later cars all have the radio suppression relay. With the problem I have as described below, the RSR would be my prime suspect. However, when I checked under the hood, it's not where I thought it should be, the left side in front of the strut tower. The normal fan relay (identical to RSR) can be seen on the right side mounted on the side of the coolant overflow tank. Thanks for any advices. Erwin


my 88 745 had some issues lately. With my limited experience on the "older" -- pre 90 cars, I still did not get to the root of it. Remembered that you've been on the Brickboard much longer than I do, you might be able to quickly point me to the right direction. Anyway, a couple of days ago, I was planning to install the seat belts for the fancy 3rd seat I found in Taylor's. It was so cold out there (11 degrees). I decided to leave the car idling while I get everything together, so when I'm working inside the car I won't freeze to death. It's probably been idling for over 1 hour (perfectly). In a sudden, the engine start to shake and died. It will not restart after a few tries. I thought that the FPR might be bad. I stick a good one in there and it started right away. However, the same thing start to happen a little bit later. That tells me that the FPR is not the problem. Last night it stalled a mile from the house with same symptoms. I managed to get it home. It's obviously the typical "warm start problem" I read so much on the board. I know with my 91 745T, it could be Radio suppression relay (the 88 one does not have such), RPM sensor on the bell, oxygen sensor, FPR, IAV and AMM (maybe). The 88 does not have a OBD readout and looks like a Bosch 2.2 (or even earlier version) fuel injection system.

Here is what I plan to do:

1. establish good solid base idle. I restored most of other parts of the car after I got it. I purposely left the higher than normal idling speed alone. For easier diagnostic, I will reset the idle.

2. Check out everything on the list.

3. and on ......
