Run fault codes and check for accelerator position sensor problem. Some engine lights do not activate for small sensor problems -just those that will cause damage to the engine and gear box.

SOURCE: Perfect Idle, no Codes, but stepping on gas causes hesitation

i would try cleaning mass air sensor, its mounted in air duct between air filter and throttle body, they sell the cleaner at auto parts stores, also as stated bofore make sure the intake pipe clamps are tight and it's not cracked, if that doen't fix it i would investigate a fuel pressure problem either a weak pump or problem with regulator

You have more than one issue/problem going on. Stop Lamp switch is the most common occurance with ESC. The other is the TPS, throttle position sensor (voltage correlation).

Have a qualified Hyundai Service Technician properly diagnose your vehicle.

I have a ford focus 56 model and sometimes it does not start no mileage working and when it does start sometimes dash lights stay on and the accelerator is slow like a flat spot.

I have a 2006 Focus and I am having the same problems. I have already replaced the battery and it hasn't helped. This is not a constant problem. Only every couple of days and then she runs fine. However I have noticed my gas peddle sticking when I first try to give it gas. Then it clears up and runs fine. Any help would be greatly appreciated.

Transmition problem

It might not be the transmission. IF your needle is dropping that rapidly, more than likely you need to have your speedometer inspected UNLESS you feel your car **** and rapidly slow down from 100km to 80km. Then it's quite possibly a transmission issue.

IF you step on the gas, and you just feel the normal light push from stepping on the accelerator pedal and your needle is still dropping and moving, have the speedometer cable inspected as well as the speed sensor. One of the two, or even both, could be causing this problem.

~Hope this helps...
