Plain and simple. I added a short ram intake and now the car wont idle. It cranks up sputters and dies. Any ideas? Its a 2005 manual box if that matters. Sensors are hooked back up.

 

check all of the clamps and amke sure they are tight I had the same prob with my cold air.....come to find out it had a loose pipe and was takin in too much air.....if not revert back to stock and see ifshe runs

 

Check all the hose connections. I had the same problem and I forgot to put the rubber hose back to the motor. That fixed my problem.

 

while your checking connections, make sure your MAF is connected good ( use some dielectric grease ) and re-set the ecu.

 

check your mass air flow sensor screws . on my one of them got loose and it did the same thing

 

Not sure about the xb but I had a similar problem with the tc and it was because the filter was very close to the MAF. I moved the filter further away and it fixed my problem.

 

i put the oem one back in and it works perfect. I just dont understand. the maf was down tight and the filter is a good 8-12" away from it. Im going to have to agree that it seems like its either getting too much air or not enough. It starts up perfect and idles down to a sputter and backfires if you dont turn the key off fast enough.

 

just reinstalled intake and bad again. How in the hell can an intake screw up the car. Ive put intakes on many of my cars and this is a first.

 

did you make sure every screw it tight, everyclamp, all the plugs and hoses are tight? and dirt in the MAF

 

totally greased around the maf where it connects with the pipe and greased around the screws...nothing.

 

as tight as i could get them. When i put the oem stuff back in, i didnt even tighten a single clamp. I just set it all in there and it started up perfect.

 

What brand of intake? Please don't say the generic one with K&N filter sold on eBay because others have posted about similar problems with it already.

 

you got it thats disheartining

 

yep those ebay ones arent well made, that;s your problem right there

 

what the heck is wrong with it? Its just a pipe with a filter?

 

probably the fit n finish is off, maf spot may not have been made well, sucking in too much crappy air

 

Have you checked to make sure that the maf is pointing the right direction? I would also check the rubber hose connoctor are sealed correctly and check the welds to see if they could be leaking too, just a thought

 

everything is sealed, it is pointing in the same direction as the oem setup, the welds look good. I emailed the seller to see if they would be willing to send me another pipe to try but we'll see. It just doesnt make sense.

I siliconed up around the maf and no luck with that either.

 

What's the size of the piping? Reason I ask is because if the size is bigger than stock it will throw off the reading of the MAF n the car will sputter, idle bad, n bog. Those generic ebay intakes r not designed like an intake from a reputable company. A good intake u'll notice is either the same size diameter as stock or there will be a section of the piping that's stock sized where the MAF goes n the rest of the intake will be of a bigger size, again this is done to insure the MAF gets a proper reading since its tuned for that size.

Another thing, is the vent hose before or after the MAF? Good intakes like TRD/AEM or an Injen has it after the MAF so the oil n other crud doesn't screw up the MAF. Most likely its either one of these things that's causeing ur car to reject the intake. U don't have to spend a rediculous amount of money on an intake like the TRD one but there is a point of being too cheap. Spend the extra few dollars on something from a reputable company n u won't have a problem like this.

 

I would say that it is the design of the "off brand".

The inside of my K&N Typhoon has a half moon section welded inside just before the MAF. all of the others I have seen have the smaller diamiter pipe just before or the half moon inset welded in.
Your probably just getting too much air ( running lean) so it won't stay running.
