Question: Service Engine soon issue

[strokin383-c4]

Here's the scenario:

Driving where ever and when I accelerate to 2-2300 rpm range my car stutters, after it stutters the car feels as if someone is tugging on the back. 5 seconds after the service engine light pops. I throw in neutral and rev to 4000 rpm, after 8 seconds the light goes away restoring full power and doesn't come on again until the net time I turn it off and drive somewhere else.

Can anyone explain? Is this my EGR?:confused

You are going to have to give us the Malf Code first.

The code needs to be retrieved first and foremost. If your not familiar, the procedure can retrieved pretty simple. Just post that up, and we can get started.

I ran it about 4 months ago, and I believe one was something021? which was o2 sensor, which i have replaced twice, and the other was something 020 or 022? tell me if I am correct.

21 is TPS signal high and 22 is TPS signal is low, 02 sensor codes are 44 & 45. There is no 20 code.
Get your self a FSM if your going to work on your own vehicle is worth the cost in wrong parts replacement cost.

like I said I dont really remember so until I can read the Malf code again I wont know, It doesnt shake any bolts on any ideas? I was thinking the EGR possibly gets stuck closed and a rush of exhaust keeps it open?
