Sounds like throttle cable.replace both, and you can adjust idle with adjustment knob look under carbs for round knob about an inch big.

Bike ldles OK with choke on.once it reaches operating tempeture the idle will drop to half the idle speed. When I ride for awhile the idle would go back to it's normal idle, about 1000rpm.


Hi Anonymous, and the usual suspects are:
1. Idle speed improperly adjusted.
2. Inlet system air leak.
3. Leaking accelerator pump.
4. Loose low-speed jet.
5. Plugged low-speed jet.
6. Contaminated or plugged low-speed circuit.
7. Enrichner valve not seated or leaking.

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 ?

Acceleration problems ,at hiway speeds, needing more speed car downshifts sputters misses then eventually snaps backto normal whats up?


Ok. I'll give you my best guess, although I am not a Dodge Stratus expert. Based upon your description of the problem, I am to assume that the vehicle has problems accelerating up to speed, but once there, cruises ok unless you are going uphill or need to accelerate quickly, then power falls off rapidly and acceleration returns very slowly. If that is accurate, I would suspect the EGR valve. This is because at ihighway cruising speeds the EGR valve is pretty much wide open, letting exhaust gases back into the intake. When you need to accelerate, pressing the accelerator results in intake vacuum drop. This is partially compensated for by closing the EGR valve. If the EGR fails to close or sticks partway open, the exhaust gases will lower intake vacuum even further, and rob engine power. This can also cause the onboard computer to force a downshift to the transmission, as vacuum sensors are used to determine engine loading and the need to reduce gearing. In addition, a partially open EGR valve can cause erratic idle as it affects static intake vacuum (EGR is normally closed at idle) and the onboard computer must continually compensate, resulting is unstable idling.

Starts great idels great give it gas and it dies


This is probably an engine using a carburetor. If it starts and idles good and dies when the accelerator is pressed it is probably the accelerator pump on the carburetor. The accelerator pump supplies the fuel to operate the engine in this transition period from idle to part throttle until the venturi effect catches up to draw the necessary fuel the engine needs to continue running at the current demanded rate of speed. If the butterflies are opened and there is not sufficient fuel squirted into the engine when larger amounts of air are in demand it starves for fuel and thus stalls.If it is fuel injected then you have other problems, but my guess is it is a carburetor version. Ford went to fuel injection in 1990. You can just purchase the power valve if needed. You don't need the complete kit. Good luck

Just put a micron can on my cbr600fl do i need to


the bike should run fine as it is. micron made the can as a direct bolt on replacement with no re-jetting required. if its stamped race use then you will have to re-jet this is usually 10-15% on main jet.
