'Hiccup' problem with K&N cold air intake! fixable?

Hello!

I installed a K&N cold air FIPK and a TB spacer as well like a week ago. I love the noise and extra power I've gained and better MPG, but sometimes when I'm floorin' it, the engine seems to studder. This doesn't happen often luckily. I might just take it in to the shop.. love the products but don't like the occasional 'hiccups' I get when I'm accelerating fast. Kind of seems to counteract the point of buying it....right? haha

Thanks!

 

maybe you are running too lean now?

with the intake and a throttle body, you get the increased air flow, but your injectors are still flowing at the same rate...

did you disconnect the battery when you installed the intake? i think the instructions tell you to... it resets your ECU and with the new air/fuel ratio, it will reset itself...

i had a similar issue when i first put my CAI and resetting the truck stopped the issues...

 

Hmmm..pretty sure I disconnected the battery while I installed everything, but maybe I'm wrong.
I'll disconnect the battery for a while and then connect it and hope it helps.
I've read that the MAS could have something to do with it, but I made sure that it's secure.

I'll try that out and hope it works.

 

I am having a similar issue on my 3rd Gen Tacoma after installing a K&N CAI. I re-installed my original intake yesterday and the problem stopped. I heard a dirty MAF sensor could cause it as well as an air leak. Did you ever find a solution to it?

 

OP is from 2012, lol...

If you have issues with your 3rd gen, try posting in the 3rd gen forum...

 

Try it without the red spacer, never had that issue ever and I put mine on new 570,000 miles ago,

 

Which red spacer are you talking about? I switched between the stock and K&N 3 times to see if I made an installation error (maybe an air leak somewhere) but the issue is still there. I don't remember seeing a red spacer. Also, my kit is the polished aluminum version so not sure if that makes any difference. Thanks for helping.

 

The red spacer by the throttle body

 

My check engine light kept coming on with the k&n so I switched to an oil free cai and for whatever reason it helped the "hiccup." haha not sure why, but 5 years later it still works great! Going o be selling the truck next year and getting a newer one..
