Hello Scotty amd everyone. I hope you guys are good.
I have a 2012 Hyundai Sonata 2.4L (non turbo) with total of 102,549 miles on it.
The problem is, sometimes not always my car's rpm is not responding to the gas pedal. It responds but its not accurate, its more like as if its lacking power. It specially happens when i try to accelerate after a stop sign or going up a bridge. But if i floor it then the car accelerates and rpm responds. At idle its all fine. I did try to scan for any error codes but no codes appear. Now this issue is not always there it happens 6/10 times. I did check the catalytic converter, ignition coils (resistance) they seem fine. Please help me its giving me a lot of headache.
Does it do the same (delayed rpm response) when you are in Park?
No. Its fine when i am at park or idle.
Have the transmission checked out by a pro.
Sure will do that.
Just a quick question. The transmission still can be a culprit if its not slipping gears or premature shifting? Or no error codes?
Because non of the above is happening.
It could be. The codes for transmission does not show on the dash unless there is a serious issue that can damage the car. You need a high level scan tool to check the tranny.
Does this vehicle have and electronic accelerator assembly? It is probably defective. If cable operated, check to cable for kinks, stretched or not correctly routed or attached to pedal or throttle body.
Thanks for the quick reply. Sorry i couldnt get that. You mean if my accelerator pedal is electronic?
Yes it is.

Well i forgot to mention that in the orignal question. I did check the throttle body position while driving. So if i press the gas, the throttle body position responds to it but the rpm doesnt.
