I Seafoamed the truck a couple of days ago, but my miss is still there. Had to make a 20 mile run in it today and threw the reader on it when I got back. Getting a KOEO code of 212, loss of ignition diagnostic monitor signal/ SPOUT circuit grounded. Can't find anything using search or in my useless Haynes manual, so need an explanation of the problem and a fix if possible. Also getting a 656, converter clutch control continuous slip error. this could explain some of the shuddering I was attributing to the engine miss. It does better with the OD disengauged, but still runs like crap

Been trying to get it running right for a month and am about at my wits end and ready to take it to the dealer along with a jar of Vaseline!

 

I found these on some other sites:
"Buy a digital multimeter & test the SPOUT circuit from the TFI to the EEC to see if it's actually shorted to ground, to power, or open. If resistance is high, try unplugging & reinstalling the SPOUT connector a few times to break up any corrosion & make a clean connection."

"I had a 212 when my pickup coil was going out in my distributor."

Sorry I can't be more help, I don't really know what those codes mean.
If taking the O/D off helps then the 656 could relate to transmission problems.

Someone else here should be able to offer you better suggestions.
Good luck.

 

Thanks Dewman,

I've already replaced the distributor, twice as a matter of fact as I thought the first was defective.

I'll do the test on the SPOUT next
