Hey , is there a way to get these fault codes scanned ?

that check engine light is on for a fault, I know you are traveling , but we need fault codes

if not

I m thinking low mileage and jeep, I m wondering if the fuel you are using has less octane then we have here and pcm learns the fuel mix

that is just guessing , the first thing if you can is pull the spark plugs & coil and check the spark plug you can look at it and tell, the ignition coil u need a voltmeter and read the resistance on all and compare if one don't match , replace

is the check engine light on or flashing?

describe the smoke ,white , black ?

please let me know

Thank You

Check all the vacuum lines and air boot from mass air flow to throttle body

The yellow engine light is solid.. The exhaust i believe is white .
Maybe i should visit local dealer here in the US and pick up leads and plugs and take to Spain for a local mechanic to fit ..What do you think?thanksPatrick

check this out

go to

you can download the 2013 jeep software in form of an app to ur smart phone,

go to amazon and buy A wireless OBDII plug

so you phone becomes the scanner, read me the faults after you replace the coils and the plugs if that did not take care of it , definitely buy the whole set of coils and plugs

if you have issues you can run a scan and that software is almost what i have at my shop scanner as far as capability of communicating with all jeep modules.

then you just post another question here and i will answer you

Expert:  Chad Farhat replied 1 year ago.

Defenietly tune parts , i like to tell you fuel filter but this one is part of fuel pump assembly

I will buy one and take with me , just in case they don t have one in Spain or probably;y have to wait to get it
