Okay, let me make sure I understand this right... you "tried to accelerate". Did the engine speed come up, but the transmission didn't put any power to the wheels?Originally Posted by VXIRONwoMAN
If that's the case, the manuals said something about it taking a few seconds to build up enough pressure in the torque converter. For a few seconds, this is normal, but if something was broken, it takes an extended amount of time.
The other way I could read it is that you stepped on the gas, but the engine didn't speed up, and in fact started to sputter.
In that case, I would check for vacuum problems. Something seems to be wrong with engine controls.
At the very least, pull out the PCV and give it a shake. If it doesn't rattle, replace it. That'll cost you about $3 and 5 minutes at the worst case.
I think you just replaced your mode switch, didn't you? So it probably isn't that.
If you've got the Torx screwdriver handy, it is pretty easy to pull out the AIC for a peek. Mine was caked with black gunk. I used some sensor-safe throttle cleaner to clean it and the throttle body.
