Probly a computr issue...dont guess on parts. Unplug it and clean pins..then plug back in..see if car reboots. If no git it scand but find anothr mech. Go to surecritic.com

A flashing check engine light means the engine is misfiring. This flashing light will eventually set a code in the low 300's. When you get the code it will tell you which cylinder. If you get a straight 300 it means multiple misfires. Right now if the light is only flashing, check the secondary ignition for loss of integrity. It's more than likely there. I hope this helps.

Fuel relay.

run fault codes and check for accelerator position sensor--- check for limp mode operation

I read somewhere that the problem was related to the sensor in the brake pedal, when it goes bad it confuses the computer, no input to indicate that the brake was applied, so it basically goes into limp mode, press the accelerator all the way to the floor and you get only gradual acceleration.

Yes this could be the problem but I would also change out the EGR valve first......Hope this helps.

Sounds like throttle position sensor is not working properly.



Good luck

I have same problem with 2002 laguna. Before warning lights and revving at 2000rpm starts car feels jumpy. Have to stop, take card out of slot and back again to start without fault. Happens a few miles drive later again. Anyone got a solution?

You probably have a loose belt.
