One other issue is that it is really difficult sometimes to put into reverse gear.
Anyone else is having the same issue?

IMHO This thread can be renamed to problems with Chevrolet Spark.

I haven't noticed such a problem with my Spark. I bought it in January and, thankfully, the accelerator hasn't come alive .

What's more worrying is that from time to time while driving the pedal comes up a bit as if it was stuck somewhere.
Also if I release the pedal the car immediately slows down.
Is this normal? Please suggest what I should do?

I had a similar problem and i realised that it was the foot mat going and getting stuk under the pedels.Just move it back for the time being and later you could change the foot mats and get new ones which are a bit shorter as in the length is less than the current ones you have so that it does not get under the pedals.

Same thing in my friends spark which i drive regularly (2-3 times a week) i guess its got to be something with the design.

Yes my Sparky has the same problem Accelerator pedal moves without any pressure and it can be felt on yout foot. After checking I suspect the floor mat, pedal rod touches the mat. Am planning to cut that area in the mat

Default Spark accelerator pedal acting odd

Already searched on the forum, and found few mentions of this behavior in spark ownership threads, but no conclusion as to whether its a feature of the spark or a bug , hence a new thread.

Purchased a Spark LT for my wife yesterday. Coming from diesel cars, i knew a few changes in driving habits will be needed.
But one thing that i noticed was that any gear change (1->2, 2->3, 3->4) if done with a simultaneous "release accelerator pedal and press clutch" operation is resulting in a 200-300 rise in the RPM. Tried this a few times to confirm, and it was happening on every shift.

So tried the following approach:
1. Leave the accelerator pedal.
2. Wait for 1-2 seconds.
3. Press clutch and change gears.

And voila! The RPM meter now behaved correctly, that is if the foot is off the accelerator, and clutch is pressed the RPM should drop once the clutch engages. The gear changes were now smoother with no over-revs.

Reached home and had a look under the dashboard. The accelerator in the spark is wire controlled. (wire connecting the pedal to the throttle body). i felt the slack of the wire was more than it should be.
Popped the hood and checked near the throttle body. The slack is such that i can lift the wire around 2-3 cms up.

This made logical sense as to why the accelerator is feeling "stuck" on releasing. The slack in the wire is not allowing the throttle body to go to minimum as soon as the pedal is released, resulting in a lag of 2-3 seconds before the rev begin to drop.

I wanted to ask if my diagnosis is correct? Is this a feature on all sparks or an issue on my spark. Is there any adjustment screw on this wire that can be adjusted at home. I am hesitant in going to the technically challenged service centres, and would like to do a D.I.Y if possible.
Would request the experts on this forum to help me out on this.

PS: checked my mom's MPFI maruti 800 for the slackness on the throttle cable and found it to be less than what is there on the spark.

This used to happen on my car too at every shift when it was new. Showed it to the SVC and as usual they said that its not a problem and you have to release the accelerator pedal fully... Somehow during the 1st Assurance check up at 1000kms, the issue was fixed. I am guessing they have reduced the slack of the wire as mentioned by you! Apologies as i am not sure what was done but the issue was present and resolved on my car.

I have a november 2007 spark which i bought used in may 2011. Even my car's accelerator pedal flutters quite a bit. And yes, even my car jerks a lot in the 1st gear.
