Ok So put this under dodge tuning because they both have the same motor and I didn't know where else to put it, but here is my situation.
I have a 2007 Jeep Liberty with 303,000 miles on it. I got it for a $1,000 buck because it didn't run but everything else was in great shape. The seller told me they had swapped out the motor from a 2002 Dodge Dakota but couldn't get it to run, and told the issue was timing. So I pulled the engine, replace a bent valve from bad timing, set the timing correctly, and It fired up on first crank. One issue I ran into was the liberty had EGR and the Dakota didn't so I used my HP tuner to disable the EGR and that issue was resolved. The only error u get now is P0507 Air Idle Control Higher Idle than Expected, I've looked everywhere for vacuum leaks and the only thing I found was the psi dropped a little with the hose the driver side valve cover was connected to the back of the manifold, i'm assuming there is a crack or just not a tight fitting, so I blocked that hole on the manifold and now I have a steady high vacuum and no more error. The only issue I can't resolve is that it falls on it's face when you try to leave from a dead stop and only from a dead stop. I did a compression check and all 6 cylinders are right around 150psi 144-155 the book says it should be 175-225, but the engine runs great at high speeds and 3+seconds after a take off but that 0-3 seconds after take off it just stumbles. I'm wondering it the timing might be off by like one link on timing chain, or still something to do with vacuum, or even if the transmission could be causing it. I noticed there is like 0 vacuum and like 0 timing right when it give it throttle from dead stop and I'm wondering if that is the issue, and if I can fix that in the tune or now. Any suggestions would be greatly appreciated. I'm also attaching the Tune file and Log file. Thanks.
Can someone tell me what is happening at 7:58:50.277, 00:04:35.275 to about 07:58:51.963, 00:04:36.961 I feel like this is when it happened.
