I own a '92 s10 wit pretty hi mileage and the only major problem I've
had was the single injector unit inside the manifold, that and the
plastic fuel lines leading to it.
About $400.00 dollars in parts and 30 minutes in my driveway and it
still runs great.
As for the wheel alignment etc, that is just routine maintenance as far
as I'm concerned.
Hope this helps.
