ya <this guy figured out fcs and rotarys are more difficult than most the hard way

 

I wouldn't say its harder

But a proper fuel system and fuel flow is the MOST important aspect of the rx7. Its the difference between build or bust.

If the injector were not firing properly and the car lean out between stages he may have a blown rotor...And 7's can run on 1 rotor and can hide the fact that you are blown unless you know the difference between the two. I would fix the wiring issue and do a test of the rear rotor...or the rotor that has the poor wiring. Anything else is a waste of time.

If you use a compression tester U need to remove the "stem" on the compression tester...meaning the tester will not hold the reading. U have to check for 3 bumps.

Example my one rotor reads: 104-100-100

 

There is no clip on the injector plug causing it to not be held on.


I am checking compression tonight, I also know how to check compression, hense 3 bumps= 3 sides of the rotor. The compresion should be between 90-115 correct?

and no I am not giving up on this car and selling it, I already took the car off the road and put my VW back on and am DDing my Jetta till I get ths car finished.

As for the rotaries are more dificult comment, I am already learning that although very different, they really arent very complex motors.

 

It runs! And has damn good compression!

 

Wow no wonder why the car ran like ass since I got it, I had already fixed 3 bad vaccuum leaks and I just did a boost leak tet and so far have fixed 8 LARGE vaccuum leaks were hoses just werent even connected, and there is at least another at least 2 or 3 leaks I still have to fix!!!!! Hopefully by the end of the night the car is gonna be running like a bat outa hell like it should! I'm excited!

 

Sweet!!

 

sounds like bad rings mike.

 

Yea, I think I might have bent a rod to

 

more likly its the lifters, when's the last time you did a valve adjustment?

 

Right after I replaced the rod bearings.
