FInally found the problem.... It was a loose nut on the tailight ground. So anyways today bought some auto meter guages for it... mounted them under the stereo. There's a tach and a oil pressure guage. but the guage came with NPT fittings and I have to find a metric fitting to convert it. Does anybody know what size the thread is on the original oil pressure sender? And should I buy any more guages to go with what I've got?
The van runs beautifully now and I'm extremely happy with the results. It's a whole lot quieter than when we got it.
Pictures coming soon.
Thanks again for everyones help!
Cheers again,
Scott
