1999 Ford Contour 4 cyl Automatic 97,000 miles

Hello! I have two separate, but perhaps interconnected problems with my ford. The first started when my check engine light came on, and I took it to the mechanic since I also needed an oil change. They ran the diagnostics, told me it was a sensor that was tripped, and then proceeded to tell me to ignore it. Twice when I have attempted to speed up onto a major highway, the car hit 40mph, started shaking and then decreased speed to 0mph. I had to stop and once I got started again, it went fine. An aquaintance had a similar problem, and the mechanics changed the O2 sensors in her car. Could this be the same problem? Also, the last two days (mornings), the car hasn't started. It will crank, but not turn over. Then, by the time it warms up outside (around 10am) the car will start perfectly fine. I had the same problem a few months ago, had it towed and the fuel filter changed, and they said that they could not replicate the problem. Could my fuel pump be failing? What types of questions should I ask the mechanic when I bring it in to be fixed? Thanks for your help!

Hi there!

I'm assuming your check engine light is still on? If so, take it to your local parts store. - AutoZone and Advance will read the codes for you for FREE as will some others.
The information your computer gets from the sensors in the car tell it what kind of operating conditions we have so that it can control your fuel/air mixture going into the engine. The check engine light comes on when a malfunction occurs in one of these circuits. If the computer isn't getting the right data, it may cut back too much on the fuel or start using more than is necessary.A warm engine requires less fuel to run than a cold engine does, so that is why you notice the difference with the weather changes. :)
If you can reply back with the troublecodes, we can more accurately pinpoint what's going on.

Thanks for your question!
Remember - your donations and recommendations keep us going!

PS - "Ignore it" is not usually a good recommendation. Especially from a mechanic ;)

After a few days of intermittent starting, it didn't work for four days. We finally towed it and it of course worked fine for the mechanic! They could not replicate the problem. The diagnostics told them that it was running lean - but that's all they said they could get without having the problem again. We live in a very small town, but I think I may know where an Advanced Auto Parts store is - I'll try that as well.
