I have a 2002 GLS elantra with 105,XXX miles. This hasn't started until a couple weeks ago and i need help. Here is my problem. I am driving down the highway between 70-80mph when i noticed my speedometer drop, nothing big, went down to 60 mph, then jumped right back up to where i was at before. No change in rpm's, no lights, nothing. The engine doesn't wind down or anything. Today while driving home from work on the highway, same speed, now the speedometer drops to 0mph, then back to 80, then to 20, back to 80, then to 0 again and hangs out for about 15-20 seconds, then right back to 80. Am i loosing a connection somewhere? I am having no problems with performance, acceleration or anything else, just my speedometer is going nuts. Anyone hear of anything like this or know what's up?
