Spark plugs/wires might need to be replaced. Check your spark plug gaps and check your spark plug module harness connection on both sides of the engine. The check engine blinking indicates short/misfiring. If there is short in the harness, you can check it by moving around the wires close to connector one by one while the engine is running. You might need to remove and ckean the Throttle Body.

Chevy Cavalier Random Misfires - Rough Idle


Try this:
-Check fuel pressure. (read in its repair manual to see how much it suppose to be.) If it's low then the fuel pressure regulator or fuel pump is defect.
-Is it fuel injector...? Then check its resistance of each injector when it's cold. If it's not within its specification then replace new one

Good luck

I have a 2000 chevy metro that has a rough idle and check engine flashes


The flashing light is indicating a misfire which is what you are describing. When is the last time you had a tune up? Most likely just replacing the spark plugs/wires will fix it.

Get a computer scan for trouble codes to see if that points you towards the problem. Possibly an engine sensor is not working right till it is warmed up. You might also check the idle air control for proper operation when cold.

Needs fuse box location and car idles rough


Fuse box is behind the soft panel under your steering wheel. Is your check engine light flashing or on? Would be a misfire causing the rough idle if it is flashing. A possible bad coil. If its just a shake with no check engine light then it could just be a motor mount.
