Hello I'm new here. Let me explain why I'm here and then get back to my question.
Well, my 1992 Ford F150 is not working and after searching the net for some ideas, the common cause for my trucks symptoms seems to be the onboard computer (EEC/PCM). I pulled my computer and sure enough there are 3 caps on the board that appear to be bad (easily move to the touch and burnt marks at solder joints). My research has shown that this seems to be common cause of failure on these computers. I can't see a manufacturer of the Caps but two of them are 47uf16v105 and one is 10uf63v105.
Back to my question "are all caps the same?". Well I'm not talking about the Manufacturers, I've seen the bad cap list and good cap list. All I see out there are caps for motherboards and nothing specific to automotive. Will these caps for motherboards last in a car computer that gets jolted around?
Will it make a difference if I use low ESR caps or not? I can't find low ESR caps in the sizes I need.
One last question. Do you believe the bad caps have affected the programming of the computer or there should be no effect at all?
Thanks in advance for your time and expertise.
