Question about 2010 Chevrolet HHR

Open Question

What is wrong with the Throttle response on my 2010 Chevrolet HHR. Can anyone help me adjust this problem..?

The problem is since I took my car to a dealer i have had this problem with my Throttle jumping slightly forward when i accelerate. I would say it's about 700 rpm. It does come back but not before it aggravates me. In short, it jumps forward and accelerates on it's own it seems.

a clogged exhaust system could cause this. Symptom would be car runs great then can't go faster than a given speed but you can cruise slower with no problems. The its gets worse over time. Always runs good at lower rpm's, then lower, then lower as the exhaust gets more clogged. Have the tech do a backpressure test

an evap vent valve malfunction generaly will not cause any drivability issues.
a surge under light acceleration and lack of power could be caused by a fuel delivery problem sutch as a plugged filter or a weak pump. it could be a malfunctioning o2 sensor or even a vacum leak.
without a scan tool to view the engine data and trouble codes, you could be in for a hair pulling experience trying to pinpoint the problem.

SOURCE: transmission jump ( kind of like a THUD sound???)

sounds like your transmission filter and fluid need changed if this is an automatic, if its a standard then your clutch may be starting to slip

I wouldn't think the PCM/ECM is the problem , hesitation at about 40 mph and 60 mph.. Something in the ignition system is breaking down causing a misfire or maybe TPS - throttle position sensor , these wouldn't cost to much. The dealer should be able to find the problem .

When accelerating the car very fast it hesitates and then jumps forward hard and then shift to the next gear. Could this be the computer.

Its not going to be smooth accelerating under full throttle. but one thing to try is disconnect the battery for ten minutes, that resets the ecms memory. but then the car will lose the zero point calibration and youll have to take it to the dealer to have it reset, which doesnt cost anything but still you would have to go. or you could just go to the dealer and have them reset your ecm for you. they wont charge you for that either.

Engine jumps while stopped. RPMs will drop or rise slightly when stopped. Problem does not persist when accelerating though.

Hey there, as far as yuor truck is concerned, you may need to check your throttle position sensor, if your truck is equipped with one, it may be bad and that would make your RPM jump and decrease dramatically....

You need to take it to a Nissan dealer and have the necessary adjustments made. The Idle Volume Learn can only be done using the Nissan Consult computer and only dealerships have these.
