Re: bogs down at high acceleration
Sounds like a plugged catylic convertor, GM has a Special Policy adjustment that covers the catylic convertors for 10 years or 120,000 miles (190,000 km), whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership. This is for 2001-2002 models with 3.4L or 3.8L engines. If you have a 3.8L engine you want to get this fixed soon, I have seen people drive these things so long with the convertor plugged that they melt a hole in the plastic intake plenum where the EGR port comes into the intake behind the throttle body.

You are going to have to inspect for a timing belt, the 1.6, 1.8 has a hydraulic tensioner if it looses its tension you wont run on all cylinder and you will bog down and yet be able to rev high. you will need to change t-belt and the t belt tensioner
Pull the plugs and look at them if they are black take a look at the carb. generally though bad plugs will give you a high speed misfire unless they are totally shot. A bog from thje carb is generally due to a bad accelerator pump (inside) or a bad power valve (also inside). Accelerator pump should give a visible squirt when you look into the carb and move the throttle linkage (do with engine off).
buy 2 fuel filters. buy can of SEAFOAM at parts store. use 1 f filter to replace old one(you'll probably see old looking gas, with an odor).Pour SEAFOAM into tank. fill up with PREMIUM gas. after about 100 miles change out fuel filter 1 last time..add SEAFOAM every 3-5000 miles and you should be fine. the ethanol in the gas turns to goop and adds water to your fuel, and puts carbon on your valves and through out your emission and fuel system. The ethanol will be alright as long as you follow these instructions. and the SEAFOAM will keep you from having line freeze up in the cold months ahead, and will give you better gas mileage. good luck.
could be trash in fuel filter or around pickup screen in tank. While driving everything sticks to them like magnet when you shut off and it sits it all falls off to happen again when you start the vehicle again
plug wires!? They go bad over time, but may still look ok from outside ... get an ohm meter and pull a wire and check ... more than 500 ohms per foot is no good..... Good high quality wires will be no more than 150 ohms per foot.
