Hey all,
Not a good night. Motor started sputtering when reaching 3000 rpm. Half-way though a tank of gas. Idles fine. No odd noises. Sputters under acceleration and in park. Google has not been any help. Thoughts? Any help would be greatly appreciated. -------------------- '99 Triple Black GT Convertible

Insufficient flow means the EGR isnt opening, you will experience increased performance and higher NO2 emissions in this case. It is not the cause of your misfire.
Check the cap, rotor and coil. Check the fuel pressure. Make sure the crank position sensor connector is clean and devoid of oil, oil can get into the wire connector and make an intermittent bad connection. This post has been edited by Special_Edy: Jun 27, 2014 - 11:07 AM |
