Sputters when RPM Reaches 3000

Pacifica Touring has trouble shifting when it reaches around 3000 rpm. It acts like it will stall out, sputtering and lurching. I let up on the gas and slowly apply pressure which allows the car to shift and continue driving. I have changed the absolute air pressure sensor, crank sensor, cam sensor and the EGR valve but nothing has changed. What else could it be?

Hello,

It sounds like it could be one of two things, first I would check the fuel pressure to see if it okay, then I would clean the MAF sensor to see if that helps, here are a couple guide to help you get started.

Hi Ken,
Unfortunately, it's not the mas or throttle position sensor but I haven't checked the fuel pressure. That's next. I should've mentioned that when it sputters and such, I also lose my cruise control. I hope it's just the pressure. I'll let you know. Thanks!
