engine stutter/putter
Here goes, my engines runs fine idle smooth and almost dead on very little hunt, smooth and powerful sounding throughout the rmp range........ that is until my coolant reaches 190deg and above. at 190deg and up when i accelerate it will stutter like its not getting fuel or spark for about 2-3 seconds at a rmp between 1800 and 2100 after it stutter it catch its self and runs fine,then it throws a code 54 "low voltage at fuel pump relay/circuit" the code goes away after that on its own or after i turn the car off . "intermintent".
after it stutters it doesnt do it again until i stop and take off again.
i already have the pfd but i would need the intermittents section b to further trouble shot.or if any one else has experienced this.
86 l98 tpi, hooker headers, magna flow catback, air removed, egr removed.

Follow the trouble shooting chart for the code 54. It wouldn't hurt to post a year. After the chart tests, check for fuel pressure at the time of failure. Besides the .pdf files, you can get your own manual at www.helminc.com.
