I NEED HELP FIGURE OUT THE PROBLEM WITH MY CAR AND HAVE NO IDEA WHAT IT IS OR WHAT TO DO

1993 Oldsmobile Cutlass • 114,723 miles

Its a 93 olds cutlass ciera, it is missing and it like runs ruff at times and sometimes its ok but its worse when ur driving down the road and when u are stopped like at a light it sounds like its going to shut off like if the battory is weak and we took it to auto zone and they did a battory altanator test they said it was ok the battory lost 2 volts and they the ones that said that it was missing and there is no engin light on and we took it for a dianstic they run it for like 5 min if that and came up every thing ok they also tested the wires and they said they are good but it still doing that some say needs plugs but I need to know what it is forshure cuz I dont have the money to fix things on the car and its not the problem. And we did have to put a new fuel pump on and filter about a month ago. And before that we did an rator flush. Also I did notis when u are driving down the road like 40 mpg and when u need to push the breaks to stop at a light the car shakes a little never done that before it started that after we had that pump and filter put on then it was notis like with in 4 hours after I left the shop like u can feal it shake and see the hood shake.

You can check mil codes, yourself. There should have at least be a code 12. How long since a tune-up? Use a gage and check fuel pressure. Clean the throttle body and idle air control.

What is engine litre size? The aldl/datalink connector is usually along lower edge of dash. You turn the key just till the dash lites com on, no further. Use jumper wire between A & B terminals at aldl. Then the mil stats flashing, you count the flashes to get the codes. Your looking for two digit codes. The idle air comrol is on the throttle-body. The accelerator linkage goes to the throttle body.

All I can tell you is what my database shows. The aldl is a diagnostic connector.

With the idle air control, look at the wire colors for the connector.
