Customer Question

Yesterday my car suddenly started shuddering while driving down the highway and my check engine light went on. The car drives but shudders. Could this be my transmission or co2 sensor? Can I drive my car short distances until I can get it to a mechanic?

The symptom you have described sounds like you have a misfire! A missfire can be caused from a bad spark plug, wire, distributor, fuel injector, or mechanical fault internal to the engine! Either way, if it is a missfire from any of these thing, the likelihood of damaging the engine any further are very low, you should be fine to drive it to the mechanic, however if you see the check engine light flashing at any point in time, you will want to turn the engine off as soon as you can as this is telling you that you are over fueling the catalytic converters and damage is eminent!

The check engine light started flashing as soon as the car started shuddering. There was no warning light before the problem. Not sure now if I can drive my car to work tomorrow. (@ 7 miles ea. way)

I would not take a chance! The catalytic converters for your car are very expensive, about $1,600 dollars! You can take a lot of taxi rides for that much! Have the car towed to the shop and you could potentially save a bundle of money by not driving it!
