My 91 has been backfiring and runnig slow. My AC pump is running with he belt on but the line by the air intake is snapped in half, should I just pull the belt, is this giving me a vac leak? or should I just let it be?

Oh also, When the car is under load the tube from the Air Pump to the Intake gets sucked in, WOuld this cause my 5/6 ports to not work properly?

The AC is a separate system in iteself, it wouldn't cause a vaccuum leak, you wanna fix the line that is crushing for sure.

well, i checked on how to fix the colapsing line, its the OEM one thats cut and run into a smaller one, from that there is a 1 foot 1/4" tube running to the Intake. Does the air to the Air Pump need to be filtered? Is there anywhere else I can run the OEM line too. This lame intake thats on the car is probly the root of a lot of my problems.

Yes the air into the airpump should go through a filter, you can always take it off and throw a small breather or something, it doesn't have to run through the same filter as the engine aspiration.

did it work out fine or no? i tried capping it off, it sounded funny and all my gas disapeared fast! i bought the car and it had a hose and clamp but it was just there not to anything. and not knowing anything about rotaries just drove around like that till i noticed.

Welcome to nopistons, Sjflowerhorn.



You're probably not going to get a response from Touya, that was posted almost 6 years ago.



However, it should work without problems, to put a small filter on the air pump intake.
