I drove the car this morning to test the rpms to speed ratio and i was disappointed once again, It took forever to get the car to warm up to C and then higher after turning on the ac. The temp needle was just shy of halfway when i began to drive. I was in fifth gear and I turned off the ac to get more power, but the temp gradually begun to fall. (this doesn't happen normally but i think this is because it was around 6:45 am) The speed in fifth gear was 100km/h at 3k rpm (i think it should be 2.5) and at 2.5k pm the speed was 80km/h. What could possibly be causing this loss of power? Once i came back home i had forgot to turn on the ac again, so the temp needle had gone back down to C. I listened very closely to the engine, my ear was almost on the valve cover. The idle rpm was around 800-900, i could hear a fast paced light clicking sound which i assume are the tappets? I don't think that they have ever been adjusted before, any thing i should know before getting them done? Also i forgot to add, my rpms on cold starts stay under 1000 and unless the car is fully warmed up to operating temp, (which is after a lot of driving and ac) the car idles at 1000. When the rpms are under 1000, there is a bit of vibration. Is that normal? Like the vibration isn't overwhelming but it is enough to cause discomfort and think why the car seems to be slightly shuddering
