89 2.5 T2 mitsu turbo W/ boostbutton SMEC Cal transplanted into a 5spd Dakota - Its been running great all summer, filled up at sheetz (93 oct) & drove it 80 miles on the highway during a heavy rainstorm, got home parked overnight on the front lawn - rained hard all night and next morning sounded horrible on startup idled around 300 and died. Now won't run right till warm (2 miles of driving to work, temp gauge reading low)...... So I'm thinking CTS is bad (it's been around 50F in the morning) and not kicking the AIS up for fast idle or richening the A/F. But I've got no codes. So I cleaned the TB (disconnected IC line but didn't disassemble things) and sprayed it good - but it's still warm and I won't know if I fixed it till tomorrow. Does my diagnosis seem sound?
