Hey everyone, need your expertise and input... The other night I decided to push my car through 4th gear and suddenly the car started fluttering and very rigid through the powerband. It was a pretty good amount. I would think it would be a misfire, injectors, or coil packs but I didn't get any codes.

There was no display of the SEIZED engine sign but the "Service Engine" light came on during the fluttering. I even ran it through 3rd gear and would get the same results.

So this morning I decided to run some logs and see whats going on... can you guys take and see if anything looks wrong. I pulled the codes but it says "No Codes Found"

Here are a couple pulls...

Here is the 1st pull in 3rd gear


Another pull from 3rd gear and SEIZED engine cut off with the 1/2 Engine Display


One last pull from 4th gear with the same results of the engine SEIZING

If the service engine soon light came on im 90% sure you should have codes. What are you using to pull them?

[Jeff@TopGearSolutions]

Yes you should have codes, atleast shadow codes. Probably misfires.

How many miles on the plugs?

[Pourky]

I plugged the USB cable in and ran those pulls... Then went to settings to read codes and kept saying no error codes.

Do I need to run the codes while I'm driving?

I have 50,000 miles on it now and not sure when the injectors were last changed if they even were. I purchased the car with 40,000 miles.

You might have the autoclear turned on.

No it's completely off. I'm not sure... maybe I should try to read the codes again. I'm thinking it could be injectors or coil packs but would that be symptoms of it?

The engine just kinda flutters through the powerband, as if a O2 sensor went out or something.
