Some Codes - Thoughts Please
My car started violently shuttering driving on the highway. Sometimes sitting at a stop light after a long drive it also seems to stutter. Just scanned it and got the following codes.
Included are fuel pump, catalytic converter conversion and a msfire. Thoughts? 2AAF: 2AAF Fuel pump, plausibility Error will not cause a warning light Error is not currently present Test conditions have been completed Short circuit or signal interruption Freeze Frame Information Event 1 Odometer 41160kms 25575miles fuel pressure before mass control valve 0.00 hPa Engine speed 0.00 rpm voltage Kl. 87 0.00 V injected mass of fuel 0.00 l/h Event 2 Odometer 41176kms 25585miles fuel pressure before mass control valve 5,858.62 hPa Engine speed 1,856.00 rpm voltage Kl. 87 13.81 V injected mass of fuel 0.00 l/h Event 3 Odometer 44176kms 27449miles fuel pressure before mass control valve 5,773.71 hPa Engine speed 3,264.00 rpm voltage Kl. 87 13.91 V injected mass of fuel 0.00 l/h 29F4: 29F4 Catalytic converter conversion Error will cause a warning light Error is not currently present Test conditions have been completed Freeze Frame Information Event 1 Odometer 41184kms 25590miles Engine speed 2,272.00 rpm air mass calculated 249.59 mg/stk Engine temperature 96.00 °C Intake air temperature 5.25 °C Event 2 Odometer 41328kms 25680miles Engine speed 2,464.00 rpm air mass calculated 282.14 mg/stk Engine temperature 82.50 °C Intake air temperature 5.25 °C Event 3 Odometer 44480kms 27638miles Engine speed 2,336.00 rpm air mass calculated 200.76 mg/stk Engine temperature 96.00 °C Intake air temperature 6.75 °C 29F5: 29F5 Catalytic converter conversion 2 Error will cause a warning light Error is not currently present Test conditions have been completed Short circuit or signal interruption Freeze Frame Information Event 1 Odometer 41184kms 25590miles Engine speed 2,208.00 rpm air mass calculated 168.20 mg/stk Engine temperature 96.75 °C Intake air temperature 5.25 °C Event 2 Odometer 41328kms 25680miles Engine speed 2,464.00 rpm air mass calculated 244.16 mg/stk Engine temperature 82.50 °C Intake air temperature 5.25 °C Event 3 Odometer 44480kms 27638miles Engine speed 2,432.00 rpm air mass calculated 265.87 mg/stk Engine temperature 96.75 °C Intake air temperature 6.75 °C 29CD: 29CD Misfirings, cylinder 1 Error will cause a warning light Error is not currently present Test conditions have been completed Short circuit or signal interruption Freeze Frame Information Event 1 Odometer 44192kms 27459miles Engine temperature 96.75 °C load value for misfire detection 92.97 % Engine speed 4,448.00 rpm Lambda integrator group 1 14.84 % |

You probably need new injectors and a HPFP with those. I had similar codes a little while back and that fixed my problems. I still get the random Catalytic Converter fault here and there, even had o2 sensors replaced (didn't fix that).

Shaking on the highway = hpfp. Mine went while the pedal was floored to merge onto the highway...pretty scary.
