So recently I've been dealing with a cylinder misfire upon inital start of my car. It starts, rpms start to drop and *almost* dies, but will come back up. It shudders while driving from the cylinder misfire, and I also hear a flushing sound when depressing the accelerator and after that.

I drive it for about two blocks, stop the car and restart it with no issue after.

Attached are my error codes. Fuel is never under quarter tank. (Evap code won't go away even after a new fuel filter and new gas cap) NGK Spark plugs are new. Spark plug tubes are new. What could be causing this? What should be my first course of action? Should I still be driving it to work?

Help! Thanks in advance.

 

Evap code could be related to the vent valve (or it's tubing) in the engine bay. Black plastic cylinder shaped thingy straight up from the s/c pulley.

I'd have a compression and/or leak down test done to eliminate burned valve or cracked cylinder head. I had the latter issue, got misfires on cold starts. Also had excessive pressure in the coolant system due to that.

Is the misfire always in cylinder 2? If so, swapping an injector from another cylinder would tell you if it's a clogged injector issue.

 

Jko has some good thoughts.

Moving you to the Stock Problems/Issues section.

 

+1 on isolating the issue. swap the spark plugs EXAMPLE: 2 for 3 does the issue follow the plug? Yes = replace the Plug. No = try swapping fuel injectors EXAMPLE: 2 for 3 does the issue follow the injector? Yes = replace the injector. No = try swapping coil pack. Visually inspect the coil pack check for cracks and signs of shorts. Also inspect the ignitions wire, cracks fouled spots and if you have a mutli-meter you can check continuity and resistance.

And the cylinder pressure test and leak down test.

A good start to help resolve the issue.

Best of luck.

Motor On!
