CHECK ENGINE LIGHT

2000 Ford Taurus

Computer problem
2000 Ford Taurus 6 cyl Front Wheel Drive Automatic 140000 miles

Ive had my taurus for almost a year, never had a problem with it. Months ago the check engine light came on after pumping gas with the car running. Rides fine, no problems. My inspection was up Dec07, took it to get the check engine light fixed so I could pass inspection. Monro said my valves needed to be purged, so they took my old sticker, gave me a 10 day and I made an ppt to get it done. After picking it up, I was pulling out of the parking lot and my light came right back on. So I went back in and they reset it and told me if it comes back on they will have to look at it again. Made another appt, now they tell me that my pcm is shot and I can only get it from the dealer, sorry. Ok but I paid over a hundred dollars for something that didnt need to be done and still my light is on. The car runs fine and is in good condition. I think he is just covering his you know what. So I took it to another little inspection place, he told me the code is 443, control valve malfunction. I have never heard of this and am wondering if this seems right. Ive already been pulled over and still cant get this light out. My question is what would make Monro tell me that my whole comp is shot and needs to be reprogrammed, which will run me around 700, after I've already paid for my valve to be purged?Are they even closely related or did I get screwed. I have no problem paying for what needs to be done, I just need it done period. Thoughts?

The p0443 code is for the evap canister purge valve, possibly liquid fuel was ingested into it during fueling while the car was running, valve works well with vapors, not so well with liquid fuel. Shut the car down before fueling, valve probably costs 40-50 bucks. Replacing the pcm is almost always the last step in a series of so-called pinpoint tests which can be run on any item in the engine management control system. Ford pcm units are pretty reliable. Chances are it's probably the valve, not 100% on that but I'd give that a try, stay away from monro, except to go back and demand your money.
