Customer Question
IH 9300 semi tractor...

IH 9300 semi tractor, have replaced 2 ECM's in 15 months. Occassionally lose engine control (truck running, but pedal appears "dead", then will recover on it's own

Mechanic's Assistant: Sometimes things that you think will be really complicated end up being easy to fix. The Heavy Truck Mechanic I'm going to connect you with knows all the tricks and shortcuts.

Ok

Mechanic's Assistant: Are you fixing your truck yourself? What have you tried so far?

Most recently we've taken it to local shop that has been successful on other trucks we use. Couldn't find the problem. It also seems to have a "flutter" when accelerating both under load and empty

Mechanic's Assistant: Anything else you want the truck mechanic to know before I connect you?

Nope. Thanks

Machine is equipped with a Cummins L10-310E engine. As previously noted, it has decent low end torque (40 ft. grain trailer), but loses RPM at higher gear ranges. When pulling a load the best we can do is 1500-1600 rpm in middle to higher gear ranges. Engine also has I would call a "flutter" at initial load and sometimes during normal running. Have had numerous occurrences of "dead pedal" when both under load and idling. ECM has been replaced 2 times in past 12 months.

Its semi truck. ***************** 2016 VOLVO VNL. Close
Hey guys, I got a problem with a truck in my fleet, I was wondering if anyone ever went thru this? So we got a 2015 Volvo VN with a D13 paired to a ishift, the truck has roughly around 700,000 miles, we bought the truck from DOT, so we do not have the full service records of it! Basically the truck runs great when he bobtails, and even when it's got a light load, but the second the truck hooks up to a heavy load, 35,000lbs+ the truck's acceleration pedal stops working, even right away when the tractor hooks up to the trailer the acceleration pedal stops working! We at the fleet replaced the main engine harness, we replaced the speed sensor on the transmission, we replaced the leveling valve in the back, checked over everything, there's no codes. Now the funny part, after a couple times of turning the truck on and off, on and off, the acceleration pedal starts working, it runs fine! Then we the driver comes to a stop or red light with the heavy load the pedal stops working again! The driver has been recently turning it off and on and offf and on, but he found a small hack, he would dump the air out of the air bags, lower them, and the acceleration pedal starts working! Does anyone have a clue what this could be?… read more
