Big problem here
Hey guys, i seem to be having some big problems with my car right now...
Here the story, friday morning, went to Midas for an oil change, then, left towards Montreal. Getting into Quebec, my engine light goes on (yellow one), but evrything thing seems to be okay but i cant stop thinking about the oil change!
Next, coming back to Toront, getting off the 401, the car starts shaking like crazy! Outta nowehere!
So this is my problem, could this be why the engine light came on? The car only shakes when im accelarating, if i let go of the pedal, it stops. But it really shakes bad, feels like if its the engine but i dont know. Could it be midas doing something wrong?
So if anyone has experienced this before let me know what happened. Or you have and idea what it can be, let me konw guys.
Thanks :cry:

If you look at his signature, it states the engine is a supercharged GSR.
First, if your going to do some troubleshooting yourself, grab a helms or other reputable service manual.
After checking that there is oil in the engine, since your car is OBD1 I would first check the trouble codes in the ECU by jumping the connector underneath your dash as it might help pinpoint the problem.
I would also be careful driving your car as when the "check engine" light is on the computer runs the car in "limp mode" meaning that it runs on defined fuel and ignition maps with no provisions of adjustment from the O2 or knock sensor.
Also, since your running a boosted car I would suspect a MAP sensor issue but would be good practice to check your ECU Error codes first.

andy yeah check and see if its got oil in it, and also push on and make sure all your spark plug cables are on tight. i had where the same stuff happened and all it was ,was a loose cable.
actually happened more then once, it bogged when ever you give some acceleration. also could be your igniter in the distributer which recently happened to me about less then a month ago.
if you can find some one with a distributer (gsr) and see if that fixs the prob.
i swapped mine and its been fine ever since.

Clear the code from the ECU by disconnecting the battery or pulling the ecu fuse(and the one to the right, I forget the name) for 30 seconds.
Start the car and see if you still have a CEL- Check Engine Light and it runs like normal, drive it.
If the light comes on again, and the ECU throws another code 41, you need to replace your O2 sensor
The O2 sensor in your car is a 4-wire (at least mine is) which has a heating element built into it. Once the element goes the O2 sensor is garbage and hence, throws a code 41. Check with parkway for a price of an OEM unit and if that is too much for you to stomach, try an aftermarket unit. OEM is best though, IMO.
Best of luck..
