Hi guys...my yaris is running rich, has poor gas mileage (360km on a full tank). and very slow and choppy idle (idles like a really old car) these are the things i have done so far : change air and fu


Do the following:
1. Clean the throttle body from inside.
2. Adjust the spark plugs gap to 1.00 mm.
3. Check fuel pump pressure. (44 Psi - 49 psi)
4. Remove the negative battery terminal for 5 minutes.
5. Connect the battery terminal.
6. Check the engine oil level and coolant level.
NOTE: Before starting the engine shut off all lights and loads for example room light, blower, radio, parking light etc.
7. Start the engine and hold the throttle at 3000 rpm till radiator fan comes on.
8. After the fan comes on release the throttle pedal and let it idle for 10 minutes.

Have a 90 f-250 5.8 gas burner. sat in a warehouse for 2 years. new battery and gas. starts and idles great. run up rpms for 2 minutes and it starts choking out. let off fuel and goes back to idling...


Carburetta is fouled. Run fine on choke - rich mixture. As it warms up and choke pulls off, its starving for gas.
First try adding fuel system cleaner to the gas tank. Do NOT go overboard. No more than double the recommended mix ratio.
The alternative is to remove the carb, open the bowl and spray out the jets and venturi with carb cleaner.

Its possible you may help it by removing the air filter and spraying every orifice you find on top of the carb. With carb cleaner. Be very carefull not to flood, pool carb cleaner in intake as this is not healthy for engine either. You can do this with engine running, so as not to pool, but slowly is best, both in engine speed and volume of carb cleaner.

I have a 1991 190e and was running on very low gas. Didnt make it to the gas station before it ran out of gas and ever since then it has been burning gas so rich and stalls out at idle or when im at a stop...


sounds like you may have sucked up some trash from your tank you can try several things a can of gas treatment a minor tune up which is changing the plugs and fuel filter you can also try a can of marvel mystery oil pour this in the fuel tank as you would gas treatment if none of this works then you can try a idle speed control sensor or a accelerator pump. hope this gives you some place to start.

Ford probe idle fluctuating


Sounds like you have bad gas. It can get strong mix of gas to give you the right idle, but when it has water mix, it will cause the car to fire like it should. This will then give you a low, rough, or just cutting off idle. Try mixing water remover in with the gas. You may have to drain the gas out or just drive it like it is until the tank is almost empty. Fill up with gas (from a different store) and you may want to change the plugs after the good gas is through the system. I'm not saying the plugs are bad, but there may be a lot of moisture beads from the water sitting causing rust.

Rough idle(rich) stalls in gear


Basically clean up before use like opening the plugs and adjusting the spark gaps, spray some carb cleaner at the intake & if The soud of the engine smoothens even slightly, then add some it to the fuel in the fuel filter & gun the engine a few time. Flush the radiator and fill in frsh coolant/water. Check the level of water in the battery and top up with distilled water. Clean the air filter and check fan belt tightness. After these small maintenace checks it should run OK.......sodeep

You need to Replace your Gas Cap. The Seal is worn and it is allowing Air to get inside the Fuel tank Causing your Rough Idle.

the ......fuel pressure regulator is on the fuel rail near the rear of the intake manifold it is round in shap. i would first check to see if you have a problem with your O2 sensors. also i would have the TPS sensor checked. the TPS is what controls your idle. it is located on the throttle body is black in color and has a weatherproof plug to it. please rate this.........thanks
