1998 jaguar xl initial startup rough, no acceleration then restarts ok
have changed fuel filter. runs good once started with full acceleration.
It takes 2 tries before all cylinders fire at startup then it is ok all day.
This problem occurs on the first startup of the day. Need the check fuel pressure when stop driving for the day and before startup in the morning.
I changed spark plugs in 2010 got 150,000 miles on car
