Hola a todos!
I own a 2010 Hyundai Sonata GLS 2.4L, 4cyl for a year now. Since I bought it, I noticed that my car had a misfiring, I did troubleshooting and I ended up checking all my 4 spark plugs on my car, now the engine light is gone and my car runs better; However, after replacing the spark plugs I noticed another issue with my car.
On highways, I have a little problem accelerating my car. Here is an example of my issue:
I am on the highway at 40mph and I want to accelerate to 50mph or 60mph, if I press the gas pedal and slowly keep pressing the gas pedal down, the car speed won't be affected (does not increase) until I really low the press down.
I hope my examples can be understood, du English is not my first language.
Here are the exact details of the new spark plugs that I put in my car if someone wants to know it:
- Bosch Double Iridium Spark Plugs 9622
Thank you in advance for the help
Does it have automatic transmisson? If so, are part-throttle downshifts working properly? (Possibly it is not downshifting until the gas pedal is floored.)
Yes, my car has an automatic transmission on it. and Yes, from what I have noticed the downshifts working properly on my car.
Maybe I did not write correctly, but that problem that I have is when I press the gas pedal my car won't accelerate until I press it all the way down.
is your throttle on a cable, or electric?
When you try to accelerate, do the RPMs go up? If so, check for low transmission fluid or a bad torque converter.
Probably a good idea to get a scanner on the car to see what code(s) it shows and go from there.
I have done that, I and fix all the codes on the computer of my car
What codes?
Does your car have a replaceable fuel filter?

Are you talking about the "In-Tank Fuel Filter"? If so, yes that filter is in good condition I inspected myself last month when I was doing a gas cluster troubleshooting in my car
Also, thank you for the link. I am looking at it now
