Why does my 2001 Hyundai accent stall? Auto Zone ran a check and these are the numbers they came up with P0108,P0300,P1123,P0304,P0303, P0302, P0301 They say AIC does not come up as bad. What do I do?

These numbers are OBD codes. They are misfire coding.
There is a youtube video to assist with troubleshooting.

hope it help

that particular vehicle has a distributor-less ignition system. completely stand alone and electronic. change around the known good coils and see if the misfires on the computer change. see, what the trouble codes say is your numbers 1 thru 4 cylinders are misfiring inadvertently. if you move the coils around, which there are 4..one to 2 cylinders and if its 4 bad coils giving problems then the codes will move around. it could be the crankshaft tone wheel or the PCM as well. take it to a good diagnostic facility like a hyundai facility if you want it fixed right the first time. the hyundai parts are a little more expensive but they are the BEST part for your car, OEM parts are the way to go and the mechanic has probably seen this before and can tell you whats wrong before you leave easily.

Change...distributor cap ..spark plug wires or spark plugs

Have you had somebody clear the codes after you installed the parts.If not the codes have to be erased by using a scan tool.

hi!

you need to scan the car to see what code its sorted in your car memory. Go to an auto part store and they will scan it for free and give you the code. Good luck

From www.hondasuv.com:

 

The P1399 random misfire along with one or more of these codes: P0301, P0302, P0303, P0304 -- indicates a problem with the valves. The B20 engines in the 1997-2001 CR-Vs are known to have problems with valves tightening and then 'burning'.

So the first question is when was the last time you adjusted the valves? If you don't know or never have, then have them adjusted. Soon...

p0456: evap system. sensor failure
p0172: evap system. intake blocked
p0778: exaust valve control. solenoid/ecu faukt
p0300: cylinders misfire. check ht/ignition leads
p0301,303,304,305,306: same ht leads

hope this helps..
