Here's the scoop on 2 problems...
My '86 9k turbo tends to sputter on rainy / damp days or after running through average sized puddles. I lose power unless the throttle is floored. Once it warms up after ~5 - 10 minutes of driving, all is fine. Doesn't sound like one cylinder is misfiring, rather, it just drowns itself out (perhaps the distributor cap rotor should be changed?). The mileage readout goes way up when this happens. I changed the wires, plugs, and distributor cap. Used dielectric grease on all contacts. Cleaned the IAC (for other reasons). I'm thinking maybe there is a problem with the air flow sensor? Too much fuel going to the engine? Any ideas?
Saabrina seems to have problems with cold starts. After sitting in the parking lot for a full day or overnight, it takes 2 - 3 attempts to get her purring. It cranks, turns over, dies immediately. I typically get her going by fiddling with the gas peddle, pumping it to maintain the rpms around 1500. Once they rpms stabilize, it runs and idles fine (unless the first problem occurs!). Note that warm starts are no problem at all.
I'd like to get these both sorted out by the end of the summer, to avoid problems during our bitter Canadian winters. Any hints would be greatly appeciated.
