Were in the same boat buddy. In my prelude I chirped 2nd gear all of this sudden my vtech goes out my speedometer stops working and my prelude doesnt want to idle at all. The first time it happened my brother in law and I started checking the fuses and relays. Surprisingly it worked all he did was mess with the speed relay. My speedometer my idle and my vtech all worked perfectly. Now last night I chirped 2nd gear and now it all stoped working again!!! So I tried messing with the speed relay and nothing this time so if anyone knows what the hell is going on please help.
