Re: ENGINE SHUTTING OFF
It can't idol you may need to shut your a/c off, take it to another mechanic, that one is a dumb @ss!
I can't believe he calls his self a mechanic.
Your idle speed adjustment screw is incorrectly tuned. When you apply
full brakes, the carburetor opening must not be completely shut off.
Also, have you looked at your temperature gauge? Your engine is running
too lean. Because not enough fuel is getting through the carburetor,
the engine runs too hot and shuts off by itself. The high-speed needle
must be adjusted so more fuel gets to the engine.

Here is a tip for retrieving Diagnostic Trouble Codes (DTCs) from any OBD1 GM vehicle. <br /><br />First thing is your going to need to get a paper clip, and bend it into a U shape. <br /><br />Now stick the ends of the paper clip into the 2 top right hand side holes in the connector. Note: Do this with the key in the run position, but with the engine off.<br /><br />You should now see your check engine light flash once, pause, then 2 times. This indicates that your ECM is working properly.<br /><br />Now it will blink indicating your code. For example an EGR failure code is DTC 32. You will see your light blink 3 times, pause, then blink 2 times, giving you code 32.<br /><br />A list of codes can be found here: http://www.gmtuners.com/OBD1_DTC.htm.<br /><br />Hopefully this helps some of you all out there. Thanks for looking.
If it stalls out when hot and then restarts after it cools down it could be one of two things. The ignition module shutting the spark down or the fuel pump shutting the fuel off. Next time it happens pull a plug wire and ground it out and have someone crank it to see if you have a nice blue spark. Be careful to not shock yourself.
look inside the computor diagnostic hook up down under the dash in your knee area but out of plain sight the look inside and find the two closest hole with a wire lug inside or most of the time the upper right two depends on how it was mount run a shunt wire or a paper clip to connect them now turn the switch on and carefully count the codes out the lite will blink for the codes and count in pairs tow quick time for 2 or once and slight pause and then two quick one's would be code 12 which is normal for trhe first code you may have to repeat this until you learn the way it work's jlelandthomas
no the obd ll is not like the older obd units where u could use a paper clip to get code ----most auto stores such as auto zone/advanced auto offer scans for free check ur local area but also check ur gas cap [for proper fit -on correctly]most common reason for check engine light good luck
The "Service engine soon" light pertains to oil change frequencies only, there is no code, it will come on at given milages to remind you to change your oil. To reset there should be a small hole in the face of the instrument panel. Remove the tiny plug and push a paper clip into the hole with a slight force until you feel a click. This should reset the light for another 3000 miles. If it does not have the hole than it must be reset by the dealer. Thank you, Dana
No you should be able to pull it. You only need a paper clip to pull it of that
Finder the connector in this picture under the driver side of the dash. With the key in the on position but the engine NOT running put the paper clip in the A and B slot (top 2).
Now the code will blink through the engine light. The first code will be 13. 1 flash STOP and 3 flashs then STOP. It will do that 3 times. After nujmber 13 that will be the problem code.
Come back and post and I will help more.
