Car stopped accelerating while driving.

Asked by GuruGTZRL Aug 17, 2020 at 11:14 PM about the 2006 Chevrolet HHR LS FWD

Question type: Maintenance & Repair

Today I was driving going about 20 MPH through
my college campus and I Started going up a hill
and all sudden I was no longer able to accelerate. I
rolled down the hill and got it somewhere safe,
luckily I had people to help me push. After it was
secure I turned the car off and on again and it
started up and was going fine. Once it started
going I noticed on the way back to my apartment
the car was occasionally miss firing, but when my
step dad came and drove it it didn't miss fire once.
I don't know anything about cars other than how to
jump it and to change a tire, so I don't have many
ideas of what the issue could be. I'm going to try a
fuel treatment tomorrow and get premium gas and
see if that helps for now. (My car has 128,000 miles
on it)

This is very often mostly caused by bad spark plugs or off brand fuses. Most likely spark plugs. The reason this happens is all spark plugs are not responding to the battery and the engine which causes it to fail it shouldn't turn off but it is normal for it to start making noises or the check engine light to turn off. Premium gas most likely wont do anything you can try it but its most likely not gonna do anything. hope this helped

that's interesting Sadeed that a spark plug would have to respond to the battery!! I've all my cars and not one responded to battery. I don't know who told you that.. the battery helps the starter start the motor thus it's ability to hold a variety of cold amps to crank the motor to begin with ( higher cca in colder areas. In hotter months 650 cc is fine. STAY AWAY from dry cell battery). So, I would try a couple of things here.. first of all, the car was operable before disturbed circuit took place ( most likely fuel relay). For a car that old, the relay is most likely old ( it doesn't help that heat and electronics don't mix anyway). Relay is a black box in your fuse box area and is usually identified on cover. This is cheap and inexpensive to replace that box. Second idea, take your spark plug wire and replace them alone with with coil wire ( I did this same thing with my Mercedes and got plenty of rush out of my acceleration ( but DONT change the plugs). After those 2 steps, if the car runs better then you know you found the problem was one or both. After that is done I would find a place to get a compression test to see if anymore work needs to be done to it and then come back to this article ( I will se you respond). Third idea, if the car still acts up I think I might focus a little harder on the camshaft position sensor. Another story for another day. One step at a time. by the way, the crank sensor reads the flywheel then tells the computer when to send spark to the ignition coil. The battery has nothing to do with that. BUT you already have crank so it's not CPS issue. g'day

Could it need a new brain? Autozone put their computer on my daughter's and it showed 4 things and it could cause it to run hot so they said it probably was the brain but it has 2 they said! Then I called local Chevrolet dealer and they said it's got 7 nodules that run electric, fuel, etc. But the car has been running rich and burning alot of gas, ac works only on high sometimes, runs rough sometimes and black sout, etc. A computer was bought for $200 by her dad maybe off ebay and he couldn't program the key to it. A friend says he thinks it's a sensor and probably fix it for $20 or less but there's a switch that has to be flipped when you change brains for it to start I think is what he told my daughter. So it hasn't run much in 4 months since she bought it because her dad didn't get the computer for several weeks and other reasons. Do you think it could be the sensor?
