The blinking light indicates there is a misfire. Have the computer scanned to identify which cylinder is the problem. Most parts stores will scan it for free. Let me know if you have additional questions.

Hi JacobandNickolas, I had the coil replaced on cyc #7. It was all melted and burnt. Took it for a test drive and still experienced the same problem. The mech. Also detected two other codes, po352 & po356 and he said that they were and interenal computer problem. The check engine light is now on steady. He stated that those codes have to do with the spark and it maybe the main computer and that it had to do with sending spark to the coil. He stated that it may happen again. What are your suggestion as to what I could do to rectify this problem? Would you know what those codes relate to? I do appreciate all of you help regarding this matter. Thank you for your time Joe.

You are having coil problems and I don't feel it has to do with the main computer. Since one melted down, I would say to check the wiring to them

Hey thanks guys I do appreciate the info. He did check the other coils and wiring and said that they were fine. He said that I may have to replace the main computer because those codes tell the coil how much spark to receive and that they maybe getting to much. The main computer is very expensive he stated like 600.00 plus and then it has to be reprogramed and then the labor cost. Those malfunction codes, are they do to a bad main computer or can this one that is in the car be reprogramed or is it just bad and needs to be replaced? He said that the computer maybe sending to much spark to the coil. I don't have the money to start spending on things that may not alleviate the problem. Would those two codes cause the problem that I am having and if so by replacing the computer will that solve the problem or is there something that can be done to fix those two circuts? You say that I am having coil problems, so what should I do? I don't know what to do with this problem and I do need to fix this. I would appreciate all the help that you can provide as you are the experts. Thank you guys for your help on this matter. You are providing a valueable service for us novices and this is wonderful on your part. Thank you again.

It is hard for me to say from here. I must say that I question if the computer is the problem. To me, it sounds like an issue with the coils themselves or the wiring to it.

Is he willing to try the computer and remove it if the problem isn't fixed?

Hey guys, thanks for all your help. I had to take it to Ford, the had to reprogram the compt as well as change out two more coils and replace the two plugs on the coils that they replaced. Should I replace the other 6 plugs so that all of them are new or does it matter. They have 75,000 miles on this set of plugs. I do appreciate all of your help and time regarding this problem. You should open a shop here in The Bronx, you would make a killing because you know what your talking about. Most don't. I think its great that you offer your knowledge in this type of forum. I commend you for that. Again, Thank You!

I hope I helped. As far as the plugs, I would replace them all. That way the cylinders will all be firing the same.
