2005 Dakota IAC Code
Hi,
I am new to this site and also very new to Dodges. I recently got a 2005 Dakota, 4.7L. It has two engine codes, P0508, and P0443. For the IAC code, the truck sometimes idles great, but then all of a sudden idles very high, then drops down to 500rpms, and will occasionally die. I have replaced the IAC, and done all the things I could find online, including cleaning the throttle body, replacing TPS, replacing all O2 sensors (had to replace the Y-pipe anyway), and checking any exposed wires for breaks or burn through, checked for a vacuum leak using the carb cleaner method, and I also checked all my fuses. I put in new spark plugs about 5 days ago and didn't notice any difference, I also checked the ignition coils and injectors while the engine is in the low/unstable idle, and they are all functioning. Is there anything else I can check, or is my best bet replacing the ECM/PCM? For the Evap code, I checked all fuel lines and connections, and did not see any cracks or breaks. I am thinking that since both codes are for an issue with a circuit, it may be the PCM not communicating properly. Any advice is much appreciated!
