Alrighty here.....a little pissed off and confused, my 02 focus is slower than ever....and with the intake on it, it seems to want to die at idle and sometimes does, to me this doesn't seem right because even with a shortram intake it should still idle fine right? Well, anyways, I was installing a jet module into my car, I got the power in, the ground, and wired into the right wires in my MAF and the TPS. Well, when I turned the module "on" the led's never lit up and it had a sudden drop in idle rpm, ran fine off though. When you rev it up in "off" it was just perfect like it was before, but when you turn it "on" and rev it up not only does it drop in idle, when you give it some gas it hesitated and died if you gave it too much. I have a strong feeling it's the MAF sensor because it's probably making it run too lean backing off my timing and such, which also adds to why I'm getting beat by everything and a geo metro can keep up.....so when the jet chip is on it probably tells the computer everything is working fine which makes it rich and screws everything up.....but idk I need some feedback, PLEASE HELP ME!

You can also pull the MAF out and spray the element with carb clean and let AIR DRY (should only take a couple of minutes) Alot of times the reusable filters end up sending oil onto the MAF element and it gets dirty. As far as JET modules are concerned, I have had little if any luck with any of there products whatsoever, but I would double check your wiring. I have never installed such a system, and I don't know why you should have to wire a bunch of crap (there is good stuff from your local diablosport dealer... ) If the car ran fine before, your MAF is NOT screwed up unless you messed it up. Put your stock parts on and make sure everything runs right there first before you condemn the factory parts. It is common to have idle issues with cold air kits (fuel trims get out of whack, ect.) It can be corrected sometimes and sometimes the kits are just junk. I would call JET and get tech from them on that problem. If it is installed incorrectly you can and will be buying a PCM, so make sure to have that correct. If it is faulty they will get it diagnosed and hopefully replaced/ repaired.
