I've got a 1998 Cobra and a check engine light. One makes me grin; one makes me mad. Check engine code is P1516, "Intake Manifold Runner Cntrl Input Error Bank 1". I'd appreciate some translation. No previous threads on MustangForums seem to mention this code... I've dealt with engine trouble and codes in the past, but this is Greek to me.

If you need to know the OBD Reader model, it's an Actron PocketScan.

P1516 - Intake Manifold Runner Control Input Error (Bank 1)
P1517 - Intake Manifold Runner Control Input Error (Bank 2) The IMRC system is monitored for failure during continuous or key ON engine OFF self-test. Each DTC will distinguish the corresponding failed bank for IMRC actuator assemblies with dual monitor switches. The test fails when the signal on the monitor pin is outside an expected calibrated range. Mechanical concern - bind, seize, damage or obstruction of IMRC hardware
An IMRCM PID reading at closed throttle that is less than VREF may indicate a fault
An IMRCM PID reading near 1 volt or greater with engine rpm of at least 3000 may indicate a fault
