i have a 2001 B2300 pickup,4cyl,5 speed. it runs great but when you try to accelerate hard below 2500 rpms it jerks and acts like it's cutting out. you can accelerate slowly and it runs fine or anything above 2500 rpms it won't do it. it seems to be the worse around 2000 rpms. i've changed the fuel filter,spark plugs,plug wires and air filter.also cleaned the MAF sensor. 104000 miles on the truck

Might be the EGR opening too soon-creating a huge vacuum leak

Suggested Repair

Check the throttle position sensor and inspect the EGR valve for opening too soon, which can create a large vacuum leak and cause jerking under hard acceleration below 2500 rpm.

Conversation Summary

The owner of a 2001 B2300 4-cylinder manual pickup reported jerking and cutting out under hard acceleration below 2500 rpm, worst around 2000 rpm, while slow acceleration and higher rpm were fine. The fuel filter, spark plugs, plug wires, air filter, and MAF cleaning did not help, and there were no trouble codes. The expert suggested checking the throttle position sensor and an EGR valve opening too soon.
