Hi guys did a long trip Monday and noticed that up hill in 4th 5th at between 70-95 full throttle I would get a like hesitation or miss fire ever like 10-15 seconds but not always but more often than not. Any ideas?

before you crank the car if you pump the grenade does it take a few pumps before it becomes hard? Are you running a lucas? is the pump damp? (could be drawing air from a knackard seal on the pump).

As for it also not starting...glow plugs all good?

Does it start easier once you've pumped the grenade?

Air getting in somewhere for sure.

Bypass the fuel filter housing temporarily and see if its better, if so get a new housing or bypass with an inline filter
