Any BTDT on R&R of Thermo Time Switch - 86 4KCSQ. Trying to get rid of my cold start problem. Swapped CSV with my 4K with no change. Think it's the thermo time switch. Is that the one at the rear of the head on the I5. The 4K mounts it in a coolant line - right? Can I just pull the TTS plug and jumper the terminals to test CSV function? Thanks for any suggestions, Jeff
