Car sometimes has difficulty starting cold (crank, no start) but that is fine now, and seems to have suddenly gotten better or maybe gone away after I checked the connection of the cold start valve.
Other issue still occurs. Start car (cold), car starts and idles normally (well, it does have many maintenance needs and a distributor shaft seal is getting a bit of oil on the exhaust manifold, but that is another issue). Drive car, OK to begin with but after not too long when you come to a stop and the engine comes down to idle, idle speed will start dropping (this is what I characterize as a stumble) and at first you can keep it up with throttle but after a few instances of this it dies. Then it will crank, but not start. If I am lucky if I wait a minute or two it will eventually catch when I crank it, but I still have to work to keep engine speed up at idle. The next time, however, it will not start until it has been sitting for a while.
I do have all the diagnostic manuals I need (EFI manual, etc.) but I am a bit unsure as to how to frame the problem well for diagnostics. It's not really a no-hot-restart issue - it's more of a driveability issue. But not exactly.
I know these are not hard cars to work on, and I've tackled harder, but I'd appreciate a bit of help if any of you can offer it. Perhaps it is because I am more focused on the rod bearing job and other work that I'm rushing to get done on another car
