Question Need help: got k&n air intake and now engine dies

I have a 2005 Dodge Ram 1500 with the 4.7L engine. I just put in a new K&N air intake on it two days ago, and it seems to be idleing low and has died 3 or 4 times when i was stopped or had it in park. Today is the first day I have driven it a considerable amount since putting on the air intake. My dad and i put it on, and did everything as directed. What could be the problem? The only non-stock parts it has is k&n air intake and Flowmaster exhaust.

Hopefully your MAF(Mass Air Flow) Sensor wasn't damaged during your swap. Did you unhook your negative battery lead to reset ECM/ECU while installing your CAI? Hopefully it's just a loose clamp or something. Otherwise, MAF's can get expensive. Good luck bud and let us know what ya find.

Uhm...he doesn't have a MAF sensor I'm almost positive. Just an air temp sensor

i suggest just double checking wire connections that you may have bumped

Yeah, I will check all of my wires. I had to drill into the air intake hose and installed the air temp sensor right, but I will look and make sure no wires are loose.

You shold not have to adjust idle in any way coming from a stock intake to an aftermarket one. We dont have a MAF but we do have a MAP sensor. Make sure you have all of your connections, wires and hoses, connected and tight and they are not cracked. Worst comes to worst, IF you did damage that in istallation, they dont cost that much to replace....i seen $40ish + on the internet.

When i hear of this problem i instantly think vacuum leak somewhere. So double check everything. Also make sure anything you may have modified on this intake is sealed. If you allow extra air to enter at the after the MAP sensor, It will run rough and die.

manifold absolute pressure sensor (MAP sensor). It basically measures the air pressure coming into the engine so the computer can regulate proper running conditions. With out it, your engine basically will not run right.

Upload a pic so i can see what you did

Side note, tjbiker031...

you seem very knowledgeable and helpful to some of these guys on here. Wish you'd come around more, we could use more guys like you.
