The new filter allowing more air into the motor throwing off the air to fuel mix ratio you can either adjust the carb or put the factory filter on

SOURCE: bogs when accelerating from an idle, rough starts.

listen for a vaccum leak.also try disconecting bat for 5 min the reconnect and start truck and hold idle at 1500-2000 for 5 min. this resets and teaches computer to self adjust

SOURCE: 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.

SOURCE: 1976 Ford F150 Bogs down when accelerater is pressed.

if it has a converter on may be stopped up, but before you replace it have the fuel pump checked, as it may not be getting enough gas at higher rpms. It will start and idle fine, but starve out when you press the pedal. Have you changed the fuel filter?That will cause the same problem.....

What would cause my 1990 chevy cheyenne to bog down while accelerating ?

The idle air control valve only controls idle speed.
The most common causes are restricted exhaust or air intake, or low fuel pressure.
Is the check engine light on ?

Starts good, idles good but bogs down when accelerating.

its the caburtor, it blocks the fuel from the pump and it also bogs out, factory fault you need to replace the caburator and bypass all the smog stuff, just install the o2 sensor into the air intak hose thats what i did

Scooter problems

most of these scooters are designed ton run lean. They will start and idle and stall out several time until warm but you cannot accelaerate without it stalling. And that's exactly what they do. There is an air adjustment screw on the bottom of the carb toward the engine side of the intake. Remove the air filter assy and use a small round mechanics mirror to look for it. When you find it use a short strait bit, you've seen them in tool kits they fit in a 1/4 inch socket but you will not use the socket just your finger and adjust out another three turns while running. This make and immediate improvement. Try accelerating after each adjustment, it should accelerate better but may have a slight hesitation yet. It may idle a little faster than you're used to but a small price to pay to get going down the highway. You still may have to move it out further. . Re-install the air cleaner this should remove more hesitation yet. These bike will also run a little on the high side on the temp guage when going down the highway. Still working on that. This is the best you will be able to do with out modifying the jets. Rob - [email protected] on vacation but will be back 7-20-08
