[DML] Re: Is My Idle OK?



All of this advice is excellant. What I want to add is that the CPR
either gets blocked up with dirt, gets hooked up incorrectly, the
hoses leak or get knocked loose, and the wiring inside can burn up.
You can disassemble it to inspect the wiring. It can be repaired but
you are better off just exchanging it for a rebuilt. Make sure the
hoses are hooked up EXACTLY as they should be and be sure they are not
cracked, loose, or leaking. You don't want to replace a good CPR just
because a vacuum hose was not on tight! A fuel pressure tester is nice
but not required. There are other ways to diagnose the fuel system.
The pressure tester is good on a car that never ran right or has weird
symptoms. If the car runs good once it warms up you can rule out most
things. Generally if you have problems during the warm-up cycle it
will turn out to be the CPR or the vacuum hoses going to it.
