Running rough

Hello,

When was the last time that your vehicle had the spark plugs changed? This is what I would do first. In the diagrams down below I have included a description of your vehicle's ignition system as well as the type of spark plugs along with the proper gap for them. I have also included a link below for you to go to.

Please go through these guides and get back to with how things turn out. There are other things to check as well, this is a good starting point.

Thanks,

would platinum plugs make a difference?

Hello again,

Platinum spark plugs are intended to last a little longer than say copper spark plugs. There are even longer lasting spark plugs on the market, say like iridium, that are intended to last a really long time. My father's vehicle, a 2014 Hyundai Electra, for instance, came from the factory with a set of iridium spark plugs and they have never been changed. He has 130,000 miles on them with no drop in gas mileage or performance. But I can only recommend the spark plugs that originally came with your vehicle, but it is just a recommendation, you will ultimately be the one purchasing them.

Thanks,
Alex

i put in rc12ecc plugs. seems to run okay,but check engine light came on and set p1762 code. did i cause that? and what is it? I turned the key on three times and it said done, then the light went out. will it come back on or should i have someone scan it? thank you for the help.

PS: i drove it about two miles and it did not turn back on.

Hello again,

Can you drive it for me one more time and if it doesn't turn back on then you have fixed it my friend. Please get back to us with what you are able to find out.
