Hello i have search the forums for days now and have not come up with a solid answer...i just bought rx7 with a mazda reman engine that is 2 years old, when i floor it there is slow acceleration from 4000 up to redline, can't figure out what the problem is, person i bought car from sd he rarely went past 4000 when he drive. Also when there is weight transfer from the front of the car to the rear the rear suspension makes the weird creeking noise. can't figure it out need some help...thanx people

 

no power from 4k up to redline sounds like your 5th and 6th ports are not opening up. You can do a test to see if they are working or not. Smear oil on the actuating rods and bring the car up to redline a few times while under load. After a few runs check to see if the oil has moved, if it hasnt ur aux ports arent working and then you can search on how to fix them. Rotaries loved to be revved. Going to redline every once in a while helps clear up carbon deposits as well but I guess the previous owner didnt knwo that.

About the squeaking noises the car is about 12 years old so the bushings are probably worn out as they are made of rubber. you could replace them.

EDIT: By the way is your car stock? if not list mods
