I drive an 09 Chevy Malibu. I’m young and live with a single mother, so it’s hard to get some help on this topic and research has lead me to so many places. My car has ran fine up until this fall/winter. The car’s Accleration has decreased, so when I try to speed up on the highway it’s incredibly slower than before. Sometimes it gets hard to break 60, I really have to push on the pedal. Also the pedal will vibrate, more the faster I go, sending vibrations up my leg. The engine noise will be incredibly loud too, louder than my radio that I will blast. There used to be humming coming from the engine, but it’s seemed to stop and only be a loud rumbling engine. To sum it up, my engine is very loud and the gas pedal vibrates a lot. My car can not accelerate at a normal speed, it takes a while for it to kick in and start going faster, and the engine sounds like it’s about to have a heart attack it’s working so hard. My rmps seem to be running higher worand jumps around unlike it has before. Also!! My gas tank, it drains soooo fast( do not know if it’s related, but I drive the speed limit and break lightly and drive only to school and work). Thank you. Someone just lead me in the right direction(:
The bearings in the engine are worn out, or the piston rings on one or more cylinders are bad. This could have been caused by lack of oil or the oil being to thick for winter.
- If it is the bearings, they maybe able to be replaced without taking the motor out.
- If it is the rings, the engine either needs a rebuild or to be replaced.
