Car has been running perfect and has always had tons of power from a dead stand still and now all of a sudden it is really slow and sluggish from a start? Change fuel filter again or what? Any suggestions?[?]
checked the line that sends boost pressure to the injection pump?.Sometimes it will pop off or get plugged.
It's the small clear plastic hose that attaches at the rear of the intake manifold,then goes to the firewall (switchover valve?) and from there to the injection pump.Mine popped off once going over the Siskiyou summit on I-5,and the power sagged big-time.
If you've been changing fuel filters regularly,your
injection pump should be fine.It will normally last as long as the engine.I would still change all three fuel filters if its been a while.....
