aiight, i was driving down the road the other day and i was coming to a stop clutch in and i look at the speedometer and tach and the needles are flipping up... i was doing like 20mph at the time and the needle bouced to zero then to like 57. now... there was a lot of corrosion on my bat which is bad to... so i bought some stuff for that and fixed that for now (what can i do to fix corrosion neways). so i thought that was it and the other day it did it again but didnt dip as much. i didnt do a very thourough job on cleaning corrosion... is that the problem? thanks guys. btw... its a vtec with 126K on it.
