Help Me Please-need advice
I have an 02 F150 4.6 and it is running super rough. At idle it "lopes" really bad. Taking off from a light is also really rough and at idle it starts to want to almost die after a hard idle. I just changed the fuel filter and cleaned the throttle body and map sensor. What else should I do (start with the least expensive)
Replace plugs? What kind do you recommend?
By the way the truck IS NOT throwing any codes.

yep, Friday when I was on my way home I noticed when I was sittting at the light it was kind of rough. It has gotten steadily worse since then. I drove it to Anaheim on Saturday you could tell it was missing on the freeway.Now it's so bad I am afraid to take it out of the driveway. I have an interview today and I will have to drive the 350, Ugh that's a beast!

Hmm I have a fancy "intake" system on there. I also have a upgraded exhust. My 2 big mods haha I also wanted to note that I took it to the end of the street and when I got back the exhust made the tinking noise for a while. Like when it gets really hot. Ron seems to think it might be the cat plugged although he also said it seems like there is air flowing out the tailpipe. Sooo hmm I don't know jack about this either.
I'm thinking plugs and possible injector failure??? Don't want to pay Ford $105.00 to diagnose and then rip me off for parts and labor.

You have the means to test injectors? Ron seems to think one might be failing but we don't know how to figure out if this is true. I checked and it's 50 bucks a pop to buy them and if I had to replace all I would be screwed since I am broke. I would be forever in your debt if you could figure out if that was the problem.
