hey everyone so the truck is just plain running like junk it idles rough, seems really low on power, and is extremely loud around 2000 rpm I have checked for vacuum leaks, and it has new air/fuel filter , plugs, clean throttle body thanks for any help

year? mileage? Anything been done to this engine before other than basic maintenance?

bill2014

101000 and has had just the regular maintenance other than the plug change and what not I just have no clue what it is?

Very common problem around that mileage would be a bad coil pack. Also sometimes when the plugs are changed, the boots from the coil to the plug get damaged, and not easy to see. Either of those will make it run like sh.

is there an easy way to test it with out a special tool

Start cheap - Seafoam it (1/2 can up the brake booster line, half in the tank). Do the diamondbird throttle position reset(free!). Check the foam seal around your air filter tray(could be the noise).

Check your FPDM - cause of all sorts of problems - seems to be different symptoms for everyone.

Have your cats checked - also could contribute to power loss and noise.

I did the sea foam trick a while ago did help a little and I made sure I got a good seal around the air filter I will have to give a those other suggestions a try tho and no the cats haven't been looked at. I meant to say it is not throwing and code that I know of( no CEL) and it seems to have a more rough idle when it is on a slight uphill slope

how do you go about testing the cop's

painthorseowner

If you have a misfire, you should have a check engine light. BUT if it is not a constant misfire, you can have a PENDING code stored on the computer WITHOUT a check engine light. Go to Autozone or someplace that will run a diagnostics check for free and see what you find.

will do I am just tired of having my truck be gutless and feel like a piece of s**t thans for the help
