If you joust the car meaning press down on the center of the rear bumper hard and let it bounce. It shouldn't bounce more than 1 and a half times that'll let you know if either strut needs replacing and repeat for the front bumper to check the struts.
To break the tie rod from the knuckle get a ball ping hammer and hit it horizontal after taking the nut off and it'll pop off. The tie rod is tapered so by hitting it makes it vibrate loose. It's better than hitting the nut on top.
Use a heat sink for the sensor in the stock location. I've had it there for over a year an half. Still accurate. I got mine off of a Chevy equinox it was on there o2 sensor. It was warrenty work so didn't feel bad.
Did you push the cv shaft all the way in till the snap ring engaged. It could have popped out and caused the vibration. Or it could be your wires causing a miss. Don't really know what you mean since there is little detail for vibration. Is it vibration from right Side of car, passenger Side...
If you can find a justice brother distributor get a bottle of fuel injection cleaner and run it in your tank or some BG injection cleaner. You could also get a fuel hose the same diameter of the injector and fill the hose up with injection cleaner. Use a hose clamp on the injector fill it up...
I have the Hyundai oil pump on my 6 bolt but I think it starting to cause noise and will probably try the new ACL/orbit oil pump and use the straight cut gears. Because if you think about the helical it would seem like it will put stress on the case. Its diagno so you would think it'll start...
Maybe you've got a dirty injector have you thought about cleaning them or sending them off to get cleaned?Wait was the car still cold when you start to get on it?
Have you done a compression test? How this system works is through the lowest resistance 2 and 3 work off the same coil so when the cas sends a signal it you have fuel in cylinder 3 that would have the least resistance so it fires but if you have low compression in that cylinder it won't fire...
Could be your injector relays in ecu causing intermitten problems but if it was transistor it would just go out and be out. But you didn't say you changed wires. You might want to change spark plug wires. Taylor's are some good wires.
