I have a '98 Ford Mustang 6. When on an incline it jerks, like a miss. Under acceleration, no problem. On the Super Slab up to 95-100 fine. It idles fine. We replaced wires, plugs, coil, all four CO2 sensors, ERG valve, ERG sensor, cam and crank sensors, three injectors, cooling fan motor. It's at the third shop now. I know other guys with the same thing.

Could this be an issue? Was the crank pulley, harmonic balancer removed or replaced?

ISSUE:

The Malfunction Indicator Lamp (MIL) may illuminate and set Diagnostic Trouble Code(s) (DTC) P0300, P0301, P0302, P0303, P0304, P0305, P0306, P0307, or P0308 on some vehicles. This may be due to the pulse ring of the crankshaft pulley and damper assembly being removed, replaced or reinstalled. This causes an incompatibility with the profile correction, or "learning", data stored within the Powertrain Control Module (PCM), which will illuminate the MIL when the engine is started.

ACTION:

Remove the negative battery cable for at least 5 minutes to erase the
original profile correction memory when removing, replacing, or reinstalling a pulse ring.

Turbochargers and GDI: A Winning Combination

Automakers have turned to turbochargers and GDI to boost fuel economy and horsepower – with less displacement.

The popularity of turbocharged gasoline engines has surged over the past 20 years. According to the Department of Energy, approximately 1% of all 2000-model-year light-duty vehicles were turbocharged. Fast-forward to today, and more than one-third of all light-duty vehicles are turbocharged.

So, why the rapid change? That’s simple: fuel-economy standards. Current CAFE standards call for automakers to increase the average fuel economy of their lineups to 54.5 mpg by 2025. To meet these regulations, automakers have needed to innovate. This innovation has led to the advent of new technologies that have changed the entire industry.
