I've got a 99 Mazda Protege (LX I think). It's a small 4cyl.
About a month ago I had a CEL which turned out to be just a dirty intake which got cleaned and everything was fine after that. I also got a tune up and new plugs etc at the same time.
Now that the weather has been cool overnight, when I start the car in the morning it doesn't have any idle strength. It turns over runs for half a second then craps out. I have to feed it gas for at least a minute or two before it will sustain a very low idle by itself. After about 5 minutes of driving the low idle gets to what I call normal. That's anywhere from 750 to 1k. When it's barely holding itself up, it's running no more than 500.
I took it in this weekend, the guys didn't find anything other than a loose hose but it did the same thing this morning. I'm looking for suggestions, thanks!
