1992 W150 5.2L MFI Code 32 & High Idle
New here and a new owner of a 92 W150. I love the truck and there are a few things I am working out on it. The two major problems are a code 32 (EGR valve) and a high idle.
The one that bothers me the most is the truck has a high idle. I didn't tach it yet, need to get a tach, but I assume it to be around 1500 rpm. After a bunch of research I believe it could be the Idle Air Control or a possible vacuum leak. I check all the vacuum hoses and the only ones that were suspect were the two connections on the 4x4 actuator. Is it possible that the IAC needs to be replaced. Is there a way to test this module?
As far as the EGR code 32 I have not been able to reset it with my OBD1 scan tool. I check the EGR valve, solenoid and all associated parts and they seem to be functioning correctly. It looks like they are new parts the previous owner must have replaced.
Any help or knowledge would be great.
