You may also notice other performance issues, like slower acceleration than usual or a stalling engine while accelerating. The smaller twin turbochargers are quick to spool and deliver a significant amount of low- and mid-range torque. However, Ford pioneered the use of turbochargers, direct injection, and variable valve timing. . Failure of any of these sensors can cause an incorrect air-fuel mixture to enter the engine, which can cause the engine to misfire. if everything is working correctly.
