alrigt im driving over the verrazano bridge..when i see my speedo is going crazy..jumping all over the place.. so i just shut the car down and restart it back up then it dies for about a min. and i restart. the speedo continues to jump then after about 5 min. of hitting open road. vtec doesnt engage at all(plus its also raining i dunno if that haas anything to do with it also the night before i had taken my ECU out of the car for the night and replugged it back in for the morning. this is a 92vx with a c1 in it..

 

Your vehicle speed sensor possibly took a **** on you.. and for the problems with VTEC not engaging.. Do you have oil, any cel's?

 

ur speedo has to be moving 20 mph+ for ur vtec to work

 

i have oil in the trans.. but today...for some reason sometimes it works when i floor it and then when i let off.. it goes back down to zero mph

 

the VSS and no vtec will be related!

My friend with a 93 prelude had the same problem, the weird thing is that every blue moon, his vtec would engage and his speedo would work. weird i tell you
