I bought this modded car about two years ago, began driving daily for about a year now.
It has cold air intake, performance intercooler, downpipes, upgraded low pressure fuel pump, and it’s tuned thru MHD
Whenever I started driving daily it flashed it to stage 0
The issues
It has misfire codes on all cylinders, rough idle, stumbles when throttle is applied, it feels sluggish. If I drive for an extended amount of time or I’m on the throttle a lot it feels like it goes into limp mode. Full throttle no torque, shakes like crazy, feels like only one cylinder is firing. No limp mode code
The weirdest part about the car is that these symptoms are not always present, they usually start to appear when the gets a few miles down the road. Whenever it gets bad enough I’ll clear the codes and the symptoms will clear up
I’ve changed the plugs and coils. I have mhd maps available, from what I can tell from the maps when the issues are present is my AFRs on both banks go crazy, all around 35-45 wot and ilde. When I rest the codes they go back to normal
Any thoughts? I’m helpless here
