Mercury Repair Questions? Ask a Mechanic for Answers ASAP
Thanks for your question. Sorry you're having car problems. If I go off line, just leave a message and I'll be right back. DO NOT leave feedback yet. The idle motor is probably dirty or defective. Take it off and clean it first, then re-train it too. Thanks, Ron
Disconnect both battery cables for 20 minutes and touch the 2 cable ends together for 10 seconds. After the 20 minutes has expired, re-connect the cables and start and drive vehicle for about 15 minutes under a variety of conditions such as idle, cruise and wide open throttle, to do a complete re-learn of the rest of the computer system.

Please note: not every answer I give you is something you were hoping to hear, even though it is true, such as; (it’s more expensive than you wanted to spend, or you will need to have a professional repair shop do the diagnostics and /or repairs due to complexity reasons).
Then the idle motor is probably defective. You will need to do the re-learn AGAIN with the new idle motor too. Thanks, Ron
OK, so you have done ALL my suggestions including the re-learn procedure. That only leaves the idle motor to be bad then and it needs to be replaced. Please don't forget to rate me as high as you see fit and I can still assist you afterwards too if you need me. Thanks again, Ron
