Car engine speed problem
My car chevy optra LS 2006 automatic, speed drops on the way and does not increase
unless i push the full gas pedal , and its get faster with great noise and jerk.
Mileage on your vehicle? Have you done any routine maintenance on your vehicle? Fuel filter? Check for codes. Autozone or O'Reily's usually has a handheld tester you can use.
Is the check engine light flashing while all this is going on? If so and you have over 100,000 miles on your Optra I suspect that you need a tune up. HTH. -Jim
