Shakes or Wobbles problem
1994 Dodge Shadow 4 cyl Front Wheel Drive Automatic 100, 00 miles
For a year now we have been having problems with this car bucking when we are driving along. Small time garages said they don't have the proper diagnostic check engine tool for this old vehicle so I took it to a Dodge dealer and they said it needed an oxygen sensor. Well it was a little better for awhile but now its doing it again. The check engine light comes on after the car is running about 5 minutes. Is it true you can get a diagnostic code by turning your key on and off three times and then check for a pattern to the check engine light coming on and off to determine the trouble?
Here is the Proceedure for pulling codes, once you get codes post them here.
To call up codes, cycle ignition switch on, off, on, off and on within 5 seconds. Stored codes will be indicated by flashes of the power loss/check engine lamp. The codes will be indicated as two digit numbers, with a four second pause between codes. An example of a code is as follows: " Power Loss/Check Engine Lamp illuminated for approximately 2 to 3 seconds as a bulb check, then turns off.
" Lamp flashes 2 times, pauses, then flashes 6 times.
" Lamp pauses for approximately 4 seconds.
" Lamp flashes 3 times, pauses, then flashes 1 time.
This would indicate that code 26 and 31 are stored. The lamp will continue to flash until all stored codes have been displayed.
Once the lamp starts flashing the stored fault codes, it cannot be stopped. If a code is missed, the entire procedure must be repeated. The lamp will not indicate if oxygen feedback system is switching lean-rich or if idle motor system is operational. The lamp also cannot be used to perform actuation test mode, sensor test mode or engine running test mode.
After all fault codes have been displayed, then power loss/check engine lamp can be used to verify switch function. The lamp will turn on and off as the switch is turned on and off.
