XC 70 Wierd Throttle (NON) Response....

Greetings from Sin City...
Strange thing happened yesterday. I was at a light, stopped and decided
to do something that is unusual for me, and that is that I put the
transmission in neutral and depressed the accelerator pedal. Nothing!
Tach stayed ad idle speed, about 1150 rpm. Took my foot off the
accelerator and stepped on it again, gradually all the way to the floor.
The engine just stayed at idle. Thinking that "something" had just
happened..."something" always happens with Volvos, I was prepared to put
the trans in drive and just let engine idle pull me off to the side of
the street. The light turned green, I put on the emergency flashers, put
the car in Drive, stepped on the gas and was off in a flash.
By the way, my XC is an '03. Driver's window was down and the A.C. was
off. I've tried the same thing about ten times since and It hasn't
happened again.
Very weird.

 

This happened to me and I re parked my2001 xcv70. I called my mech. he said to turn the key to off position then restart the car as normal. I did this and every thing is ok. (My guess is a fluke with the computer, and I reset it?)
