Drowning sound around 3-3.5 rpms

I recently put on a K & N intake hoping that it would make my truck run better. However it did not. It made it sound like its drowning at 3-3.5 rpms when over 1/4 throttle and it barely keeps accelerating.

I've already checked vacuum hoses, cleaned my Maf, changed my fuel filter, and have (currently) running injector cleaner (sea foam).

Any help would be greatly appreciated!

I know i said 3-3.5 rpms but its actually 3-4.5rpms

 

try disconnecting the battery, push the brake pedal to the floor for a few seconds and letting it sit for a few minutes to reset the ECM.

Although i doubt something so severe is from the ECM/ECU not catching up yet.

How did the truck run prior to the intake?

 

i'll try that, and it was throwing the PO171 code before then i put a new o2 sensor on
, and it was still throwing the code after i reset it,
but other than the check engine light it didn't run like there was a major problem it just didnt run very good

 

get it rescanned or scan the codes if you have an OBD scanner. Maybe something new? And when is the last time you changed plugs/wires?

 

i changed plugs and wires 6 months ago or so.

here is a link of it accelerating

hmmm thats really weird, im kinda glad i didnt order this last week...subd to see what could be the problem good luck tho!!

 

sounds fine to me

 

was the vid with WOT ??

 

Ya it sounds great! But it just won't go, it takes likes 20 seconds to get to 60 with a v6? Idk what the deal is, it runs a little better in overdrive I'll put up a video tomorrow.

 

Yes it was 1/4 at first till it got to like 15 then it was WFO

 

ohhhh i see. huh. that is weird

 

watch from :15 to :26. It takes over ten seconds to get from 3000rpm to 4000rpms...not right.

 

yeah i get it now. i thought the OP was talking about the sound of the engine

 

seems like an ignition problem to me

does the CEL flash when it does it? (dont know if its in the view frame in the vid)

 

Put your seat belt on.

Then try some seafoam. Directly inject a bottle into engine and put a bottle in your tank to clean your fuel injectors.

 

The CEL doesnt flash it just stays illuminated.

 

I haven't put seafoam directly into the engine put i have a can in the gas tank currently.

Where do you directly inject it into ur engine?

 

So your check engine light is on?..... Get that fixed first....

 

Break booster vacuum line? Do a search, lots of threads on this.

 

Speaking for the OP...I dont think your paying enough attention the the video, ignore the sound. Watch from :15 and on... after it shifts...it takes over 10 seconds to get from 3k to 4k rpms...something not right.

OP also said he cleaned his MAF.
