Solara started idling very rough.
Although seems to run fine on the road
I changed the Throttle Positioning Sensor, but no difference
checked for vacuum leaks did not see any. Ignition Coil Packs seem to be okay
Diagnostic code showed that cylinder one, three and five are not firing. Could this be the Idle Air Control Valve
or if not, is it possible that the timing belt has jumped?
