I own a x reg. escort van with a endura 1.8 non-turbo, cav pump
done 100k miles belts last changed at 82k
on driving the running feels lumpy with small surges of power nothing serious but irritating on idle the engine seems to waver in speed slightly.
changed fuel filter (very little water in filter contents) and air filter.
have thougherly bled system (including loosening injector unions)
cannot see any vac pipes connected to injector pump to check.
any suggestions or am I looking at new injector pump?
