Diagnose this: poor starting when cold
Posted 04 February 2010 - 06:44 PM
It seems like it has to be electrical because it runs fine after it starts. I didn't have this problem in prior winters. Any ideas. What could I try to diagnose it?

I'd also try some strong fuel system cleaner. (it never really hurts)
Check the resistance of each of the spark plug wires when they're cold with an ohmmeter. They should all be fairly close in measurement, if not then get a new set.

How old is your timing belt by the way?

I don't see why the temperature sensor would cause it, but it's something I never thought of and it's cheap to replace.

I'll go to my U-pull-it junkyard Monday and see if I can get a CTS. Thanks for the advice. Thankfully someone put pictures on the internet or I would never be able to find the CTS.

The wires seem OK. I hate to change them too.
What does "seem OK" mean? Did you test there resistance with an OHM meter?
Or did you just look at them?
They should eb replaced every 30k miles.
If they are red "Yazaki" wires, then they are the originals and DEFINATELY need replaced.

So now I'm giving the car a couple tankful treatments of Techron. I'm hoping that one of the fuel injectors is partially plugged and the treatment will clean it out. But the weather in Wi is warming up so there probably won't be any real cold mornings that I can check it out. I'll find out next winter.
Thanks for all the help and suggestions.
