Finally got the exhaust uncorked on #181, so the wife and I decided to drive the cars on some twisty backroads.
Early on I attempted a pass on a slower vehicle, and the car just fell flat. On. Its. Face. Plop.
It refused to rev, and I absolutely could not get it to respond to any throttle input. The first time I stopped, I was looking for vacuum hoses that may have blown off (or apart), nothing was obvious. At this point I decided we needed to return to the shop, since it was still running and driving and I did NOT want to have the car towed.
I kept stopping and popping the hood, looking for things that I was thinking may be the problem...nothing doing. Meanwhile, temps even in the north Georgia mountains were nearly 100 degrees, higher still on the two lane blacktop we were standing on.
Finally, during one stop I blipped the throttle (easy to reach, also useful as a diagnostic tool) and promptly saw the intake hose suck shut. What the #!$?
Upon arrival at the shop, I was thinking about what on earth would cause so much of a pressure drop in the intake tract to suck it shut...then it dawned on me.
I pulled the air filter...or what was left of it. Apparently, during my pass, the engine tried to eat the filter, and the plastic cone was a perfect fit on the wire screen in the MAF...It nearly completely cut off air flow to the engine. Swapped out the filter, et voila...pulls like a freight train again. I imagine the glue on the old filter had given up and allowed it to spontaneously disassemble itself.
Anyway, too funny not to share.
