I accidently put premuim gas in ny 02Protege (only 1/2 tank) now my check engine light went on...should i be worried?? how do i know the problem is the gas i put in? car runs fine...


Good Morning

Dont worry.

The check engine light is telling you something, but not that you put the gas in the tank. Probably an emission system gone haywire for a bit.

Autozone will check the light for free when you get a chance. But it is NOT the gas, so dont worry about it ...

Have a great day

My car was running beautifully, had a oil change and filters change, again drove beautifully for 3 days, then overnight, it starts great, but shakes between 5mph-25 mph, and is sluggish when i take off...


Have your fuel filter changed, your fuel filter may be at the end of it's life time and is dirty. The fuel filter should be replaced every 15,000 miles or once a year to ensure that the fuel system is running at 100%. Try that first and if there is an Auto Zone around your area, have the car scanned for the DTC codes. Auto Zone scan free of charge and can give you the recommended steps to addressing the issue that is causing your engine problem. Good luck and keep me posted, be glad to help you get your car running 100% again soon.

My 2002 Z24 Cavalier surges on take off.


Fuel pressure and fuel filter can cause this to happen. The tuneup being past due can do it too. The check engine light may be on and if it is the codes need looked into to go after something the computer can't work with like a bad throttle position snser. or over senser out of range. Some sensers don't code as their still working but not right

It sounds like it's gonna die when i start it, like it don't want to stay running, but it don't die. could it be bad Gas? i just changed the fuel pump 3 months ago. any help would be nice


Hello and yes this can be bad gas. This also can be something that can be fixed with a simple fuel or air filter change as well. I would do a basic tune up of spark plugs and wires which may fouled out it sounds like, oil and filter, air filter, and fuel filter. I would also change the distributor cap and rotary button. These few tune up items may help your rough running automobile. If you have any other questions email me and I hope you resolve this issue.
