Hi so my 15’ GT has been having some issues it was throwing three codes p061a pcm code “internal torque calculation error” and it also had two rich codes for both sides of the engine. The car hesitated on accelerating felt slow and just felt generally bad to drive. Anyway I couldn’t figure it out so I bring it to the dealer for a diagnostic. They couldn’t figure it out best they could say was my autolite spark plugs. They had the car for about a month and now I have it again and they didn’t really do anything but the car doesn’t seem to be throwing any of the codes it used to before and now when I step on the gas it goes and seems to go just fine. But when slowly accelerating especially up hills the car struggles it feels like it loses power and just generally doesn’t want to go in the 2.5-3.5k rpm range and just doesn’t feel smooth but no codes are thrown. the car almost feels like it’s inching forward like the torque curve isn’t smooth at all. Im actually just at a lose with this. The autolite plugs have less than 5k miles on them and I recently replaced the fuel injectors which also have less than 1k miles on them. Dealer said fuel pressure was fine so i’m just at a loss any thoughts would br appreciated a lot. thanks guys. UPDATE code p061A came up again “Internal Control Module Torque Performance”

 

I am way out of my depth here, but it sounds like it relates to the computer's "torque management" logic/software that works with the engine and the transmission to supposedly optimize how it is responding to throttle, shifting, etc.

Since it might be a flaky computer issue: "Have you tried turning it off then turning it back on again?"

Half joking, but -- you might want to reset the computer by unplugging the battery for a while (about 20 minutes to be safe), to give it a reboot. This clears the "adaptive learning" that might be messed up and gets you back to "default." I believe there is also a way to do this with software such as Forscan through the OBD2 port. If there is some corrupted data in the computer, this might clear it. It might not help, but it's easy to do and might be worth a try.

 

Dealership reset everything, ECU, PCM everything. They even reflashed a stock tune onto the car.

 

So Does the Car Have Other Mods which the Stock Tune May Not Play Nicely With???

Straight pipe from the cat back, CAI that’s about all the engine mods but it should be able to handle just those two things

 

As I was reading I was also thinking your cats are getting clogged or are close to it. Just a interweb mechanic guessing more or less. When was the last time the TB was cleanned. Throttle pos sensor feeeeeeeling fininky maybe?

 

Most CAI's require a tune. If that CAI requires a tune, car will not run right with factory tune. That probably isn't the original problem, but it will be an ongoing problem, if not corrected.

Key to know is: does your CAI require a tune?

The reason the tune is required, is that the mass air flow metering section is bigger than the original one; and if the computer's math is not corrected with the tune, it will do bad math and probably run lean.

 

Intake doesn’t require a tune i’ve had it on since i’ve had the cwr and it’s ran fine up until a few months ago

 

No cat codes but I’ll try checking tps and tb out dealer said they checked it but i’ll take a look for myself

 

Despite no cat codes, I would still have your rear 02 sensors looked at just to make certain anyhow

 

If the dealership cant fix it in a week or two I would leave it sit there and waste time
