Hi,
My car Mazda 626 '91 exhibits some strange behaviour in humid (rainy) weather. When I start it cold, the engine does not idle smoothly, and has some sort of vibrations (fairly quick ones). This is an engine with the injectors.
When trying to drive, the engine power is low, and I can hardly accelerate. Again, there are these quick shivers coming from the engine. The problem seems to disappear at high rpms while the engine is still not warmed up, like > 2500.
Then, when I drive for 10 minutes and the engine temperature is at its high level, the problem kind of goes away and the car works fine. There are no problems in dry weather.
The problem does not reappear if the car sits for a while, not too long though. I think this is while the engine is still warm.
On this newsgroup it has been suggested that some of the electrical wiring could be bad.
Does anyone recognize these specific symptoms?
Thanks! Mike
