Ok tonight on the way home from the mall I am driving my womans 1998 civic Lx Sedan. It is an automatic, well we pull out from a toll booth onto the highway and I floored it and we hit about 4K rpm and the throttle sticks! It shoots to 5 grand so I throw it in nuetral and it keeps revving till about 7K so I shut it off and right around redline and pull over. I put it in park and start it up and it runs fine. Floor it to try it again and its fine! What could have happened? Pedal stick? Throttle under the hood stick? I looked at it and it was really dirty and dry greasy looking. Throttle cable fucked? Could it be her auto tranny? Car only has 45,000 miles. Thanx for the help!
