rough idle on cold start
I bought 2001 3.0 tribute last summer and there was no problem until the summer was over. I'm in cold area, Calgary Canada, by the way.
I'd noticed rough idle when cold start in the morning around October and it's getting worse(sometime stall) as the tempature went down. Once the engine tempature goes up to normal, no more rough idle.
I've also noticed that if I use "block heater" during the very cold days, rough idle is not so bad.
Finally, I got the engine check light on, so replaced spark plug, fuel filter, air filter, IAC valve and ECT senor by myself. Sadly, I still have the rough idle in the morning.
Are there anything I can do before I go to mechanic or dealer?
Please help....
