:{ Long Story short: I picked up my 98. 5 after extensive A/C repair including pulling the dash. Experienced many non-function problems, took it back. Now, no power and I get an rushing air noise that at first I thought was the A/C in cab fan. Rolling down the window, I hear the same noise outside but louder. Noise comes on at about 1/3 throttle. Replaced the air filter, which was ~60% clogged, helped a little. WOT at 30mph held for 5 seconds or so only gets 2600 RPM and 1 to 3 mph increase. Also, the transmission (auto) does not seem to know what gear to be in. I'm headed back to the dealer but I would like some ammo to take with me. Any constructive help would be appreciated.
