Will a cylinder head from a 1996 honda civc 1.5l non vtec work correctly on a 93 honda civic 1.5l non vtec


The 1996 civic has a 1.6L b-16 engine. The only difference between the v-tec and non v-tec engine is the dual overhead cam i believe. The 93 civic also should have a b-16 engine in it. The cylinder head should work.......

Hyuandai high idle speed when in traffic


You don't, unless it's ridiculously high, like over 1750 rmp. Most cars will idle higher in drive then they do in park. The next time you get caught at a light put it in park and let it sit, it may go higher at first but most lower below what it was idling.

93 cavalier vibrating


your probably feeling a rough idle of the engine. need a tune up?

in park the engine is not loaded down, just idling at a low rpm=rough
in drive with brake on you have put some load on motor also at low rpm=rough
in drive on the road engine is at higher rpm, = smoother

generally 4 cylinder motors idle a bit rough, especially if one spark plug is not firing right or fouled or one bad spark plug wire. tune up may fix it. if it is not stumbling real bad or stalling then you can live with it.
