Rough idle/no start
Hello I'm a newer owner of a 2004 jeep grand Cherokee with a 4.7 and it's been a great ride untill recent.
I went to start it Sunday and it was not the easy one turn of the key start up as it's been, it was a rough start followed by a rough idle and dying out if I gave it gas. It was giving the p0171 and p0174 codes. I checked for a vacuum leak and checked the tps and iac which I cleaned because it was nasty looking and still nothing wouldn't even start. Have great fuel pressure so i ruled fuel issue out. I'm not a mechanic at all but I do know a thing or two and can figure things out but this has me lost not being familiar with a jeep.
Thanks for any help

Have you recently replaced the fuel filter? I've read some aftermarket ones can cause this.
And you checked and got a vacuum leak, can you elaborate? This could be the issue as well.
