so my samurai (when it's cold out) take forever to warm up, if I try and start it and go, I just trot along real slow until it warms up...do all older samurai's do this, also my samurai tops at at 55mph on flat, is this normal? the fastest I've ever gotten it to go is 70 but that was going downhill for a long time....just wanted to know if all older (87) samurai's do this or mine is just a crappy one...
