SOURCE: clicking noise when accelerating
Hello, this noise may be a stuck or warped lifter. This also can be a warped wrist pin or a thrown bearing. I would check and see if your oil is sludgy for a lack of better words for starters. I would check your oil level as well. Your valve lash can be off as well and this can be thrown off by this causing the ticking noise you are talking about. Is the noise coming from the top or the bottom of the motor. I hope this helps. Thank You.

SOURCE: weird squeaking noise from under
You should have your belts checked for proper tension. If they're squeaking when the engine is at a low RPM then they are most likely loose and need to be tightened. However, that squeak may also be an indication that one of the tensioners in the belt's line may be wearing down. If that is the case the tensioner will need to be replaced since the bearing inside is worn down beyond the point where lubrication would be useful.

Did the vehicle have this problem prior to replacing plugs?If not check that you have the leads on the correct plugs.If you could supply the model I may be able to give you better details and diagnosis.Some of the later models had coils on each plug so they are all a little different to diagnose.
I hope this helps,or get back with some more info
