Thank you immensely for your response ;)
Yes, the check engine light is on. He did do a diagnostic and it did come back with a hit on cylinder #4 so he said it was probably a clogged up fuel injector and/or a fouled out spark plug so that's when we did the plugs and wires and gas treatment and good gasoline and all that. The engine light went off and it was great for a day and now it's doing the same thing.
Let me ask you this.I looked online at a service bulletin for 2001 Ford Focus and in 2004 there was a fuel delivery module defect so I have Ford looking at it now.(I know they can probably figure out what my problem is immediately and they can fix it, but I'm trying to save some money b/c I don't happen to have an extra arm and leg.) Anyhow, they said that since a problem is present, they'll check the fuel delivery module and see if it needs changing. Do you think this might be at least part of the problem?
Will a defective fuel delivery module defect cause my plugs to foul out?
I can't figure out why the car ran like a dream for a day and then started doing the same thing again almost immediately. It makes me feel like something is causing the plugs to foul out. Is that what it sounds like to you?
Thank you so much for your help, you have absolutely NO idea how much I appreciate this.
