Question about 2000 Ford Contour
Replaced the spark plugs and the wires the fuel injecter#4 oxygen sensors a vaccum hose still not running right
Sounds like your spending alot for this problem.....if this problem is only one cylinder then changing the fuel pump won't fix it...try removing the plug wire to each cylinder one at a time while running and monitor the RPM drop for each cylinder, they should be EVEN....If not thats the bad cylinder....at this point you need to check the cylinder compression in each cylinder...they should be within 75>80% of the highest reading..if its lower you have mechanical problem..(valves/piston/etc)...if good compression then your problem is fuel/electrical..this requires testers if you got them great.... if not then....at this point I suggest take it to a dealer/shop to save you any more undue parts cost...hope this helps you..GL
