Hello,
I have a question about the possibility of a link between a bad IAC valve and a loss of oil pressure at idle?
The specifics are, truck has been running great. Only major thing so far has been fixing the rear timing chain. Truck has 180K miles on it with regular maintenance. For the last 6 months, it had at times idled a little rough, but nothing serious. Just got back from a cross country trip and had no issues, but it was a hot drive. A week after returning home, she would start up and almost instantly die. I could eventually get it started, but it took some cranking. The next morning I checked the IAC valve and cleaned as much of the carbon as I could and also checked the oil. It was low, so I added some Lucas oil treatment. It started like normal and idled good, but the oil pressure gauge jumped around a little. After driving for about 15 minutes, stopped at a light and the oil pressure gauge bottomed out and the RPM at idle seemed really low (under 500). Tapped the accelerator and RPM and oil pressure went back to normal until it idled back down.
My question is could the oil pressure issue be caused by a bad IAC valve or should I begin preparing myself for bad news? I should add that when at low idle/bottomed out pressure gauge there is no change in how the engine runs or sounds.
Thanks
