About a month ago i turned my car on one morning and the mil was on. I scanned and found a dtc p0135 was there. I went to run some errands and noticed the car didnt want to pass 2000rpm and had a serious lack of power. Finally after about a mile or so the car jerked forward and off we went as if nothing happened. I cleared the code and it drove normal for about two weeks. Now everytime i start my car and drive away. It does this thing where it wont pass 2000rpm for a few seconds almost as if its about to cutoff then it lunges forward and drive normal for the rest of the trip. This is just about everytime i start up and drive off, doesnt matter the ambient temp or coolant temp. There are currently no dtc's present. Can somebody. Give me a bit of insight as to were to look, or if maybe this is some type of common issue etc.
