i have Freightliner with MBE OM 460 LA engine that is hard starting, no check engine light, only ABS tractor light is on, and no codes shown when scanned with a nexiq graph scanner.it starts only when you spray diesel into the air filter. did a compression test with the scanner, and got these readings: #1cyl=99.21%,#2cyl=100%,#3cyl=99.21%,#4cyl=85.93%,#5cyl77.34% and #6cyl=61.71% I'm confused on the way forward
hard start for MBE 2004
