Before anybody asks I Have been searching the Internet and threads for the last 3 days And have found no definitive answer I am having an issue with my type S as the rpm raises above 3500 it starts to stutter When this happens the engine light flickers but never stays on it drives fine at a steady rpm and only happens under acceleration there's no Codes pending or stored It has clean oil i replaced the spark plugs with ngk iridiums and made sure that the vtech solenoid was clean Any real information would be helpful

 

Mis-fires would be the only function that "blinks" the CEL without it staying on solid... and this may be caused from a lack of fuel. Check fuel pressure and consider issues at the fuel pump. Also, a loose or corroded engine harness ground can cause load related issues, so check that ground (found on the top edge of the intake manifold between the middle two cylinder runners OR on the middle valve cover nut closest to the intake manifold).

 

Thank you ill look in to this in the morning hopefully it leads to something that will fix it
