Question about 1996 Pontiac Grand Am

Engine light flashes when going up hill.

I have a 96 grand am. When I am going up a hill the engine light starts to flash, but when back on level ground the light stops. The spark plugs and wires were changed, and rechecked. They seem ok. The car also lacks power when going up hill.

Sometimes when you are going up hill your check engine light or your oil light will come on because all of the oil is at the back of your oil pan.

96 Chevy Suburban going up hill the battery light starts flashing and the battery gauge drops. As soon as you level off it all goes back to normal. Have already changed battery, alternator and a wire


Wow, thats pretty weird.
The only thing that comes to mind is a bad connection in the harness somewhere that would be affected by engine torque.
Can you make it happen if you power-brake the engine ?

I have a 96 grand cherokee.when i come to a stop it stalls and as i hit the gas to resume driving it studders and struggles to pick up speed


Are you check injection system? Some check engine light there; try read fault codes stored on ECU under this procedure...


Without starting the engine, turn the ignition key on, off, on, off, and back to on.


The "CHECK ENGINE" light will flash the first digit, pause and then flash the second digit of any stored error.


Example:one flash and pause and eight flashes = number 18 error code.


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Where can find the plug to get cheek compuetr in grand cherokee 94


1994 is before OBD II, so it won't have the plug your thinking of. Here is the procedure to get the trouble code(s) if the check engine light is on. MIL is the check engine light.

MIL Method

This procedure may be used on 1991-96 models.
  1. Start the engine, if possible, cycle the transmission selector and the A/C switch if applicable. Shut off the engine.
  2. Turn the ignition switch ON-OFF, ON-OFF, ON-OFF, ON within 5 seconds.
  3. Observe the MIL on the instrument panel.
  4. Just after the last ON cycle, MIL will begin flashing the stored codes.
  5. The codes are transmitted as two digit flashes. For example Code 21 will be displayed as a FLASH FLASH pause FLASH.
  6. Be ready to write down the codes as they appear; the only way to repeat the codes is to start over at the beginning.

What engine code(s) are you getiing? Try cycling key to, on ,off, on, off, on & leave on. (not start)
now count flashes from check engine light. will be flashes, pause ,flashes for 2 digit #'s. For example: 2 flashes , pause, 2 more is code 22.
3 flashes,pause, 3 more, is code 33. Write them down & get back to us. By the way when you get 55, thats end of message.

have someone scan it for transmission codes. Most likely it is your Torque Converter that is going out, but it could be a solenoid, What color was your fluid?
