Questions about Fuel Systems

I think you may have hit the nail on the head. We have not checked under the injector manifold. BUT, I did get the idleing problem fixed today. Tightened a pin under the throttle linkage and it smoothed right on out. Thanks for the help. Now it's time to work on the Volvo.

Thanks. Working on that thing is tight quarters and the parts aren't exactly cheap. I just hope I can get another 185k out of it.

try replacing the fuel filter first. it's a little interesting to work on... bolted underneath, has those silly spring clips on it, you have to bleed the pressure off first at the fuel rail... but you're due on that. aftermarket filters from a quality source like wix should be less than the dealer cost. any decent auto parts store will have a filter for that vehicle in stock.

2002 Silverado, 8.1L, 73K mi. - This truck has seen a gradual reduction in fuel mileage over the last six months. Besides plugs, what constitutes a tune-up? Should the injectors be removed and cleaned? as well as O2 sensors? Thanks.

"Besides plugs, what constitutes a tune-up?"

Plug wires, air filter, PCV valve, fuel filter.

"Should the injectors be removed and cleaned?"

No.

"as well as O2 sensors?"

No. Oxygen sensors will gradually deteriorate, and when they do they'll tend to slow down their response to changes in exhaust gas oxygen content. The proper way to check an O2 sensor is to monitor it's activity on a scan tool, watching for swings between low and high voltage output.
