2011 Acceleration problem
Looking for some help. My 2011 Grand Cherokee with a Hemi has been in the shop for 4 weeks now and the dealer canít find the problem. The issue is acceleration, it has a very noticeable dead spot until you get over 3000 rpm then it pulls real hard. On a rolling stop it is very noticeable. The dealer has replaced the computer, a cam phaser, wiring harness. The car is not throwing any error codes at all and they canít seem to find the issue. They did disconnect the IAT sensor and it does run better but is getting like 12 MPG and of course the check engine light is on. Looking for any ideas or suggestions?
