Engine Performance problem
1993 Mazda 626 4 cyl Front Wheel Drive Manual 125000 miles
----------------------------------------------------------------
Car is idling low , base idle was reset at dealer about a year ago due to same problem , 5 min and 95 bucks , I read somewhere but can't remember where that it can be reset through the DLC by grounding a pin , if so which pin and where is the dlc on this car . Any help appreciated

The DLC is on the drivers side near the power distribution box-jumper TEN and GND then adjust it see below-also do the computer relearn

Is the DLC under the dash or hood , are the pins numbered for easy ID or do you have a pic . Thanks

Its under the hood next to the power distribution box-it will show the pins under the cover

Here's a good picture of the leads...and how to read trouble codes, you might want to do that first!

Where did you get that Mr. Merlin -the best thing I can do is give the 1993 MX6 info which I have one on hand 2.5 Liter- TYVM

The Mitchell1 procedure you sent in your response for relearn drive is cut off for the manual transmission after the first line , can you include it please , also is the pin 10 grounding procedure done key on engine off .
