MY check engine light came on today. It would flash then stay on solid. Then flash again and stay on solid. It is really bouncing at idole. I checked my gas cap and oil and it all fine. I hope this is not a major problem. All i have is an AEM V2 CAI for years. This is the first time I have seen the CEL light on. What should I do?

 

Go to autozone and get the code pulled.




Peace

 

If it's flashing do not drive the car!

 

Dun't drive it anymore till you pull the codes.

 

It flashes then stays on solid for a min then flashes again and goes to solid.
i wont drive it, only to get the code.
thanks for the reply.

ill let you know whats wrong.

 

Flashing CEL = misfire DTC's. Which ones you won't know untill you get the codes.

 

Flashing CEL=car is undriveable. Autozone lets you take the obdII sensor home (for a good while too) so grab another car and get taht code pulled.

 

i have the codes (4)

P0304
P0303
P0300
P1399

Random missfire in cylinders 3 and 4.
Anyone had this? and what to do?

 

oh the pain.... start praying now. maybe its something electrical but I had similar problems that were caused by the valves not seating properly Run Compression.

 

You have two mis-firing plugs as evidenced by your codes (303=#3 cylinder misfire/304=#4 cylinder misfire.....300 just says random misfires) The key code here is the intermittent 1399 which is why you OBDII is on again of again as a critical failure (i.e. blinking CEL). My guess is that somehow your ignition coil connector has become loose. Reseat it and see if the blinking goes away, If it does then you are clean and can remove the battery termnla to reset the ECU. If reconnecting the Ignition connector does not fix it the yo need to take it to the dealer so they can pull the whole series off OBDII.
