Hello everyone, I have been troubleshooting various electrical issues for months. I am fixing the issues as the occur, however one issue I cannot seem to determine the cause. A 1999 Grand Cherokee WJ with an intermittent low idle complaint. The idle drops to 300 rpm in drive only. I currently have no trouble codes. I have checked all sensor voltages and they are all correct. I did change the TPS and the IAC anyway, but the issue is still occurring. Not sure where to go from this point, so I really do appreciate any help or suggestions you can provided.
