What happens when a fuel injector goes bad?

ok so here i am again about my 2001 ford windstar, the problem started with my spark plugs the garage has my van now and he tells me the valves went bad because the fuel injector was spitting out to much gas and when it does that the only out let it has in threw the cylinder thats why it was burning the tip off the spark plug and when they heely coiled it ...it wasnt able to spit the spark plug out so it like almost vacuumed sucked the valve back into the head so my question is when they changed all my spark plugs it was fine before i just took it into have a tune up..so is this something that just happens or did the garage to something to help this to happen?What happens when a fuel injector goes bad?First off all, too much fuel will never burn a valve or ruin a spark plug on any gasoline engine on the face of the earth. *Take that to the bank!



Too much fuel may foul a plug making it look black or dark and cause it to misfire. *Too little fuel will burn valves, valve seats, turn spark plugs white, burn spark plug electrodes and burn pistons.



If the fuel injection nozzles were dirty or partially plugged you'd get a lean mixture in a particular cylinder.



It's time to change mechanics or take your Ford to a Ford dealership so they'll know what to hell they're doing



The garage didn't hurt the motor. Something is causing what ever cylinder your having problems with not to be getting enough fuel.

%26lt;-------Tisha, See my name, when a fuel injector goes bad..............it just stops so called spewing gasoline into the piston chamber period. Then the chamber would run dry, decreasing your gas mileage. When a fuel injector sips out too much gasoline, it can damage the cataytic converter, damage the Oxygen sensors. Sounds right to me that all you need is a new fuel injector and some fuel system cleaner

if the car was OK.. until you go to them for a tune-up ... that`s all you need to know.

I never heard about this problem at any ford. Still ...the injector can put to much gas. In this case you push the pedal to much, so you should have a huge gas consume and a big speed. If the valves are bad, they should charge you for valves, gaskets, oil %26amp; filter. This parts are not more then ....$200. Now depends how much they will charge you per hour. to take the valves back. By the way.... if they change the valves, tell them to change the belts too. ALL of them. Sometimes after you change the valves, you can broke them if the timing belt broke. Anyway, next time, try to find a mechanic on www.craigslist.com It`s way cheaper and they are doing a good job. They need money not like the garages. I hate to put any car in any garage. All the garages look for customers.... and they will do something bad with your car to make you come back. You can e-mail me with more questions at antistres@ymail.com if you have any doubts.
Wow what an unintelligible tale. Sorry miss makes no scene. Your car was spitting plugs from the head? HELI-COIL installed? %26quot;so it like almost vacuumed sucked the valve back into the head%26quot; WTF? All I can say is get this in writing or get to another shop.
