Gents,
Now that I have idle issues mostly sorted out, I've got another issue to take care of.
After a few dozens km on highway the engine temperature starts to climb into 220F/105C area. Usually my commute ends by then, so I don't know if it would go up any further. Now, if only left to idle, the engine temp is fine. I've also noted that it seems like temp goes up faster if I drive with higher rpm.
My car has an original AC heat exchanger mounted in front of the radiator, but I keep the AC off - the compressor is disconnected. So theoretically it could be that the heat exchanger disturbs airflow, but I've got a couple of friends with similar Spiders and they don't experience such high temperatures while driving.
I did full radiator cleaning about 800 miles ago (the car was parked for 12 years before that) and after that I've flushed the cooling system about 3 times, last time using dishwasher descaler.
Ideas on what could cause such behavior?
