Hi, This newly aquired Mazda failed smog check.

Ignition timing needs adjustment, under the hood it says to jumper as to adjust idle speed, I don’t know where to jump in the diagnosis block.

A MIL code also failed but the amber light in the dash doesn’t light up at all, nor the turn signal lights. Should I try replacing the bulbs first?

The car hesitates upon acceleration a bit but seems fine with 240,000 miles.

The car is for a student and I’m trying to help out, with your help too. Thanks in advance.

Get a Haynes auto manual. For $14.95, it will help show you lots of information to get this car tuned-up. Not all MIL codes will turn on the CEL. To tell if the bulb is burned out, turn on the ignition, and all the dashlights should light up for a couple of seconds. If the CEL doesn’t, then the bulb is blown.

The MIL light doesn’t light at all, nor do the turn signal indicator or backlights in the odometer/tach panel, nothing lights up in there.
If I want to adjust the ignition timing or the idle speed, then I need a Haynes? I know this community has knowledgable mechanics.
Can anyone tell me how to jump the diagnosis block so I can adjust, the timing and idle speed, sort of jumper thing?

I found out how to do the timing, jump ground to ten, adjust idle, then timing.
Replacing those tiny instrument cluster lamps should be fun. I hope the air bag is not upseted. Any coments would be apreciated. Thanks.
