Hey guys...weird question for you. I have a 96 turbo prelude, everything has been working fine for the past few months.
All of a sudden I'm driving it in the rain yesterday and I don't know if it's my imagination or not, but I punched the gas, boosted from 5mph to about 45 mph, let go of the gas and I swear the speedometer needle was just floating around 45 mph, even after i let go of the gas. It seems like it's delayed or something?! From a stop, I drove normally and I'm not sure but it seems like it's not moving until a sec after I am actually rolling, like it's giving my speed 1 second ago instead of right now.

It snowed 6" after I got back home, so I haven't been able to drive it since then. You guys think it's just a fluke from weather? One of those things that just goes away by itself? Or is it at all possible that somehow I punched the pedal hard enough to mess up the throttle cable or speed sensor near the wheel?

Oh yeah, I don't know if this has anything to do w/ it, but after the delay, I tried flooring it and my AFC read out throttle 96% instead of 100%.

 

Since you didn't get another chance to drive your car to see the problem.. this may or may not help but my friends VSS(vehicle speed sensor) went out on him. He had a 93 prelude too. His speedometer just stopped working, his vtec didnt kick in anymore and he got a CEL 17 which is VSS.

 

i would check your volatages or just make suire it is connected i had that problem in the rain one time in my 95 accord but i was bruning out and hydro plaining.

 

Thanks for the help guys,

Will check it out as soon as the snow clears out. Don't exactly wanna boost on ice
