Peterbilt Issues: Everything You Need to Know

Hard Start Issues

One of the most frustrating issues that Peterbilt 359 owners face is hard starting. There are several potential causes for this problem, but the most common ones include a faulty starter motor, a weak battery, a clogged fuel filter, low engine compression, or low cranking speed. In some cases, hard starting may also be caused by a malfunctioning fuel pump or injector. At EIP Diesel Repair, our technicians are well-versed in Peterbilt trucks and Cummins engines. We use the latest diagnostic equipment to pinpoint the exact cause of the problem, and we always use high-quality OEM or aftermarket replacement parts to ensure that your Peterbilt truck is good to go.

Running Rough

If your Peterbilt 359 is running rough at lower RPMs, it's likely due to an issue with the fuel system. A dirty fuel filter, a clogged fuel injector, or a malfunctioning fuel pump could cause this. A rough ride could also be the product of issues with the engine's air intake system, such as a clogged air filter or a faulty mass airflow sensor. If you experience any of these issues with your Peterbilt 359 truck, swing by our shop to get it fixed.

EGR Valve Leaks

Another common issue that Peterbilt 359 owners face is EGR valve leaks, a notorious problem in Cummins engines. The EGR valve is a crucial component of the engine's emissions system, and a leak can cause a variety of problems, including reduced engine performance and increased emissions. Our technicians are experts at diagnosing and repairing any after-treatment problem, including EGR valve leaks, ensuring that your Peterbilt can continue to meet all emissions standards.
