So my car's stuttering when going WOT on higher gear 4th and up......right around 4500 rpm.......

I was able to get a SES light, but when I read the code on the Procede reader, it read: 1023.000 ??

Anyone know if this is a misfire or injector related?

I should have some new plugs by tomorrow......

TIA

How many times did the SES flash?
Recent recalls/software updates

Answer those as best you can. Did you email Vishnu about the code?

my car did something very similar when the valves were gunked up pretty bad. Once cleaned the car ran like a champ. My car had 45k on it though.

It was above 4500 and was a weird hesitation feeling, almost like you were being pulled back and it had a slight shake. No CEL... They finally figured it out after replacing everything.

How many times did the SES flash?

None, it went into limp mode the first time. Second time, it threw the SES light. But both times the car drove like crap afterwards........

Recent recalls/software updates

Did the injector recall and software update, I believe it's the latest one that has to do with emissions?

No.

My car's outta warranty now, but is that hard to do? To clean the valves or whatever?

TIA

It didn't blink at all.....

I've never seen the procede give a code with like that. I've only seen the 5 digit ones. When my car had similar behavior, my fuel pump was on the way out.

EDIT: Can you do a run with the car and log fuel pressure, CAN Actual Ignition, Throttle, CAN DBW Throttle, AFR, boost, and RPM post it up. Maybe that would give a better idea about what is going on.

[Joe@TopGearSolutions]

Normally if the SES blinks twice it was an over-boost. Overboost is common on the latest DIC maps. Change your overboost from the default 10 value to maybe 30 and see if it happens again. Shoot an email to Visnu otherwise.

If the code was 10230.00 instead of 1023.000 then that's 27F6 which apparently is "Pedal Travel" or "Pedal Value Sensor" so I guess it could explain the stuttering if the car can't read the pedal position?

How did you clean the valves?

Ah, you're user software doesn't have the CAN DME Codes parameter set up to read codes properly. You are probably running and old datalog set-up file. Or maybe even old user software. If you download the new software and dump in any reasonably recent datalog set-up files, you will be able to read the code.

But everytime I update the user sw interface, I always drag and drop those two files for datalogging in the procede folder......is that what you're referring to?

TIA

Mind showing me how to properly setup the parameter to read the codes correctly?
