I have recently read comments about a vacuum pump causing the old I-5
knock at 2750 RPM.I posted that to the list as my problem quite awhile
back, and got a variety of responses. Since, I have changed lifters, and
done a bunch of other crap-- to no avail. What I have not done is look
at the vacuum pump-- I didn't even think that those of us without turbos
had a vacuum pump. S0-- do those of us with normally aspirated 5ks have
them? and where are they?
Also, the girlfriends '90 cq has a steering wheel wobble between 60 and
70 MPH. We have balanced the tires and had der dealer even check the
differential and a bunch of other things-- his diagnosis: the wheels.
The car has Moda 5 spoke wheels, and der dealer claims that they need
hub-centering rings. Calls to the tire rack say that those wheels never
need hub centering rings-- they have an adapter plate. I am tempted to
believe anyone before I believe the dealer, but I am lost for solutions.
Happy to be re-subbed and employed (for awhile, that is),
