Temp 2 sensor and idle speed controller (assuming 2.1L). As for grounds the ring terminals can be clean and tight but wires can be broken inside the insulation and the wire-wire crimp connection can be corroded enough to be a problem. The idle speed controller and ECU both use the temp 22 sensor. Both go to one side of the sensor and the sensor sinks the current to ground. Any bad connection confuses both. That is why I suggest troubleshooting taking measurments before moving stuff. Only way to know what was wrong and what actually fixed a problem.

I have just returned from a successful post re-build road trip with 1400 miles on the clock. My only issue seems to be a hard cold start issue. The engine will fire right up, stall and then will require a bit of gas to get it going again. After it is warmed up it runs like a champ. Everything is new on this engine. I did a complete tear down, all bearing, seals, new AA 95.5mm pistons and jugs, remanufactured Go Westy heads, all new sensors, exhaust, cat, o2 sensor... The grounds are all clean and tight, so I am stumped on the cold start issue. Any ideas on where I should be searching?

Thanks, Finn Runyon Taos, NM 87 Westy Pooh 89 Westy Roo
