Check engine light and ets light come on and off on 96 cavalier
The check engine light and ets light will come on and stay on for about 75 miles. They will both go off and maybe stay off for 50 miles. The lights come on and off intermittently. I had a code check done at Autozone and a code 440 was detected. I had a new gas cap put on but that doesn't seem to fix the problem. Can anyone assist?

Check for bad spark plug cables and check all the plugs. Take out spark plug cable one by one and crank engine to check if there is spark or not. Before you head over replacing expensive items in this car get a compression check by mechanic for each cylinder. For a car this old and so much miles on it, most probably it needs an engine rebuild.
The ETS light is the warning light for the Electronic Traction Control. Check Engine light indicates there is a problem with the emissions system. Take the vehicle to Auto Zone, Advance Auto Parts, O'Reilles, or Pep Boys and have the ECU scanned to see what codes comes up. The code will tell your what part is being effected.
ETS is Enhanced Traction System is used to stop wheel slip thru reducing engine output. And if the light is on it doesn't mean you will spend x amount of dollars to fix it! It just means that ETS has been disabled because you have a engine problem and the computer cannot reduce power to the wheels because the engine might stall so the computer disables the system! Now some cars come with a switch by the shifter that turns on and off the system because if you get stuck in the snow traction control will keep you from getting stuck
You need to put a code reader on the car to retreive the codes .The trouble code that caused or is causeing the problem will show up and lead you where to look and if the code is not active then the reader will be able to turn out the light.[Check your gas cap to see if it's tight].
Theres a funny thing with ETS and engine lights in the cavalier. first check the gas tank cap. mame sure it is closed down firmly. If it already seems like it is firmly in place - try a different one from a friend or something like that. when there's air inlet from the gas tank, apparantly the car lights the check engine light becaues air inlet from the gas tank messes with its mixture values.
