Here are a the TPS specs: Have you tried drying out the engine bay with compressed air or even an leaf blower ? Maybe water got in a connection somewhere. If you can take the TB off and inspect the plugs for pooling of water on the head They are kind of deep in there and do not dry out easily by themselves. Seafoam shouldn't cause the symptoms that you describe. Are you able to take it out on the highway and run it for a while to heat up everything under the hood and dry it out ? Let us know Also just replace the PCV valve, They are inexpensive. Another thought, You may have fouled a O2 sensor with the seafoam and the ECU has not cycled to throw a CEL.
Thanks for the response. I pulled a plug out and it looks ok. No water pooled up on top of the plugs. I could leave one out and see what it kicks up at me when I try to start it.
Can't get it on the highway because I can't get it into D. It dies as soon as I try to shift it.
I was thinking about a bad O2, but there are so many of them, and they aren't cheap, so I want to move on to that possibility last.
Where is the PCV located? It doesn't seem to be in an obvious spot up top, or else I'm looking right at it and not seeing it. Maybe the passenger side of the engine, where the line runs to the intake?
You might be able to clean the O2 sensors (be careful, Don't use anything abrasive, Maybe some alcohol ) Here are some pic's of the PCV, Drivers side of the head near the firewall.
