Like the title says i just bought a 1990 300zx N/A. :woot: It has 135k miles and runs fine minus it needing a new injector. Took mufflers off today because of tiny leaks in each one so its loud as F**k. Changed oil with royal purple and replaced spark plugs. When i shift it hard its almost like the back right side jumps a little from left to right? Anyone know what could cause that? New to the forums so any help is much appreciated! Thanks!! :dblthumb:

Probably worn out differential/rear subframe bushings.

If one injector is going the others probably will follow soon after it they are original

What plugs did you put in, these cars don't like most plugs, and even though they are expensive the best and sometimes only way to go with factory spec
