cone air filter messed up...

Okay... I bought this *bomz racing* filter and adapter off of ebay... and when i installed it my truck ran really rough. I checked all of my sensors and they are fine.. i just cant get my computer to adapt to the new changes... i reset it.. no luck.. took off neg. battery cable.. no luck.. i tried it all.. so if any one has any thoughts i would LOVe to hear!!! thanks all!!!!

I am assuming it is like a KKM unit. What did you do with the vacuum hoses that attached to the bi-metal sensor on top of the Stock airbox? The hose running to the intake manifold must be capped off to prevent a vacuum leak.

i too had this same problem when I made my own adapter. DeRocha, I dont see any vacuum hose that went to the air box anywhere. Anyone care to chime in with some pictures or something

I do believe those hoses are only for first gens.

I noticed those vacuum lines too, (1994 xlt) when i removed the bimetal sensor from the stock air box I just put it back and attatched the lines again.. i thought maybe i had them crossed.. so i switched them.. still no luck.. ive heard that the tube between the maf and the throttle body, if cracked, can pull more air in with a better filter that the maf cant detect (after the sensor) i found a few small holes.. and patched those up with goop.. i cleaned my maf sensor and my iat sensor.. i guess im just running out of ideas. for now i have my stock air box until i figure this thing out.. thanks for all of your input!!! any more would be greatly appreciated!!!! thanks!!!!

My 99 did not have that vacuum line on the stock airbox. However by the sounds of things vacuum leaks are ther first thing I would check for. The propane torch method (UNLIT) will work well to exam all those connections and help find the culprit.
