No matter what operating condition (short of demanding more fuel than the pump can supply), pressure in the rail will always be 58psi (or pretty close). When idling at 20 inHg, this means effective pressure will rise to 68psi because the vacuum in the manifold is adding 10psi to the rails 58psi.

- The exhaust gives off fuel smell.
- Low fuel economy and constant refuelling.
- Poor engine performance.
- Blackened spark plugs.
- Spark plugs that are wet with fuel.
- Restrictions in return line.
What happens when a lambda sensor fails?
If the lambda sensor is defective, no data will be sent to the ECU, which will then use faulty information. This will most likely increase the fuel consumption, and subsequently, the polluting emissions. Eventually, this may lead to the clogging of the catalytic converter, which you will then have to replace.
What does lambda sensor do?
A lambda sensor, or oxygen sensor, is a vital element in your car's emissions systems, ensuring that your fuel mixture has the right amount of oxygen for efficient and environmentally-friendly combustion.
Can you drive with a faulty lambda sensor?
Yes, you can drive with a bad oxygen sensor if you can still start your engine and feel little difficulty driving. But don't leave it alone for over a couple of days, as it might cause safety problems and lead to the malfunction of other parts of your vehicle.
What causes lambda sensor failure?
Lucas said: “The lambda sensor operates in extremely high temperatures so damage to the heater element of the sensor is the most frequent fault associated with this part. “Vibration or damage to connectors and/or wires can also cause failure. “Another common cause of premature failure is contamination.
Can you idle a PACCAR engine?
If idling for extended periods of time in extremely cold ambient temperatures, it may be required to increase the engine speed above 850 RPM. Idling at this slightly elevated RPM generates the necessary heat to prevent components from becoming clogged with soot.
What RPM should a truck idle at?
about 600-800 rpm
When should you idle a semi truck?
Both extreme cold and extreme hot weather, can present conditions where the driver may find it necessary to idle the truck, in order to be comfortable. What is this? However, it can be a dangerous practice, if safety precautions aren't followed. Idle the engine at 900 RPM to 1200 RPM.
How long can you idle a semi truck?
Running the engine allows the air conditioner to run, so the driver can rest comfortably. Some diesel engines require a cooldown period before shutting off. This means the engine may be left to idle for up to 30 minutes after the vehicle is stopped.
How long will a PACCAR MX-13 last?
The MX-13 engine — and the MX-11 — offers a B10 design life of 1 million miles in linehaul applications, which means 90% of the engines will log up to 1 million miles without a major overhaul, according to Bellevue, Wash.
Can PACCAR engines be rebuilt?
MX-13 Overhaul kits, liners & cylinder heads are all in stock and only available through PACCAR Parts. All kits contain only PACCAR Genuine Parts, allowing you to restore a PACCAR MX-13 engine to its original factory quality level, giving confidence that your PACCAR engine will provide many more miles of service.
How good is the PACCAR MX-13 engine?
The PACCAR MX-13 engine brings efficiency and flexibility together into one, high-performance solution. The first new rating of 405 hp and 1,650 lb-ft of torque provides constant power for line haul applications, enhances integration with the PACCAR Powertrain, and offers increased fuel efficiency.
