O2 Sensor question

I have 1990 900 TC. It runs absolutly like heck when I start it cold. Misses and stuff like its running on 2 cylenders. for the heck of it I replaced the plugs, wires, rotor and cap. the code is related to the O2sensor. I tested it and have power to the plug, roaming voltage from the black wire. The only thing is the book says I should have 4oms at the preheater and I have 7.6oms. Is that too much resistance and its not preheating properly.
Once it gets over the missing, in a few minuts, it runs sweet..like it used to.
The hole thing started after washing the engin, which I have been doing since I got it many many years ago.
What could it be???????
