Q: Service engine light is on and blinking when started?

asked by on January 11, 2018

? I replaced the coil and crankshaft position sensor plus the cap n rotor plus wires n spark plugs r about 4 months old
My car has an automatic transmission.

The check engine may be blinking due to computer sensor or misfire issue. Have the computer scanned to get the failure codes and then have the codes diagnosed. You may have a lean injection system causing misfire when first started and may have low fuel pressure also.
