Since fixing my AW71 tranny ('93 944T)I have been driving without any problems through rain, snow, ice, sunny weather her in West Michigan for 1,500 miles. Until this afternoon after I went for lunch. She started fine drove fine to the restaurant (5 miles).
After lunch she started fine I backed out of parking space and when trying to pull into the road she bogged down (no power) she would idle, but stalled when applying gas. I noticed check engine light. Pulled aside started her again but could not get rpm over 1500 in neutral/park. Shut her off, started her again and was able to rev her up. Not to hold traffic up behind me I pulled away from the traffic light and she seemed to be fine. Stopped again to visit a client and 15 minutes later she started fine, drove fine, but still shows check engine.
Is this a fluke with just a bad start/OBC due to 30 deg F (-1C) and high humidity (snowing) weather.
An inspection under the hood did not show anything visual wrong. I hear a lot of talk about diagnostic codes on this forum,
Where can I find these codes?
Do I need a special tool to extract these codes?
Is there a list of what the codes are?
Does a disconnect of the battery terminals reset my light?
Thanks,
