Hi guys, so my car is at 160k and i though of doing a regular tune up in which i replaced the spark plugs, ignition wires, caps and rotor, valve cover gasket, oil pan gasket and transmission filter and gasket changed as well. So after my mechanic put everything back and i took the test drive my car was having jumpy idle, jerking alot while taking off from a stop and while coming to a stop and also i experienced little jerking while driving at 40mph. Can anyone hel me out? I put ngk laser iridium spark plugs and ngk ignition wires following up with royal purple 10w30 high mileage engine oil and royal purple max atf tranny oil and royal purple engine oil filter.

 

I forgot to mention that my car is 1990 model.
