bad experience & why it's important to keep OEM parts

[todd95GT]

I purchased a Densecharger system for my 95 Mustang GT. When I received it, I was a little upset that I would have to drill into the inner
fender of my car, unlike other cold-air systems. But, I did and made the installation.
On two separate occassions, the throttle body inlet tube came off of the mass air flow sensor. One of those times was on the interstate cruising
at 75 mph when the car began stuttering and the check engine light came on. Fortunately, nothing got into the intake tract to the throttle body. About a day after I installed the setup, I noticed that the idle had become slightly choopy and that when the car sat idle for more than a few seconds, I could smell the heavy odor of gas, as if the car was burning rich. For the next few weeks, I clocked and averaged my fuel economy. I went from approximately 18-20 mpg down to 14-15 mpg. From
nearly 300 miles per tank to around 220-230 at best. I spent time and money purchasing new spark plugs, cap, rotor, wires; adjusted the timing, had a professional shop flush the fuel injectors, etc. Nothing helped. When I realized that the idle would fluctuate from 700-1100 rpm's, I disconnected the battery for the second time since theinstallation and let the car sit for twenty minutes or so. After reconnecting the battery, the car would idle normally again for about five minutes, then back to the same old thing: smell of gas, poor economy, rough idle.
Finally, I replaced the Densecharger system with the factory airbox and factory replacement K&N air filter. Everything is now fine again. I
spent two hundred and fifty dollars tuning the car up plus the one hundred for the Densecharger system. So, $350.00 later, I'm back to where I was before I bought it, only now, I have a box of plastic tubing and an unusable K&N filter in my garage.
Point, ask before you buy and SAVE THOSE OEM PARTS!!! Forunately, I saved everything and was able to put it all back on with the exception of a new K&N.
I'm going to wait on mods for now since I recently bought a new block and crank to start on an AFR headed 347.
