My truck is a 1994 k1500 with the 5.7l. I have fixed a few issues with this truck from the previous owner, including re wiring the IAC valve, replacing the o2 sensor, and fixing the vacuum line from the map sensor to the throttle body. All were easy and fixed all the codes. Now the truck is not throwing any codes, but wants to idle really low, somewhere around 200 with extremely low oil pressure, and wants to stall out. When the truck is first started up it sort of pulses with the rpm gauge until it calms down and then idles very low. I had heard this can sometimes be caused by a faulty ground wire, as my oil pressure gauge is erratic but eventually lets me know where it's at. Any advice is appreciated!
