When that happens, does your check engine light come on? If yes, take it to your local auto parts store and have them read the code with their scanner.

If the codes do point to a faulty cam or crank sensor, then all u gotta do is replace them. They are all pretty easy to change. But ONLY use OEM replacement sensors. These cars dont work well with aftermarket sensors. All 3 of em will cost about $300 total.

The problem typically occurs within the first 15 minutes of driving but not the first minute or two.

The most common symptom is from a dead stop there is a hiccup around 2k RPM. Ill start driving and the engine will rev to around 2k and the car will start moving and then the RPMs will fall to around 1200. Then the car will keep moving as normal, but the hiccup can be obviously felt.

Occasionally, around 2k RPM the tach and car will start stuttering. This has gotten worse and worse over time. It will be a +- 200 RPM stutter that gradually gets worse unless I step on the gas quite a bit. It is difficult to explain, but had anyone had this and found out what it was?

I'm really hoping it is not the transmission because I do not have the money for that right now. If anyone had any diagnostic help or advice that would be greatly appreciated. I will Venmo anyone who finds the correct fix 25$ if that motivates anyone (sorry I'm a broke college student).

Thanks!
