Hey guys. My 99 mounty(SOHC V6) recently started having an interesting problem. At random times it will stumble when accelerating, sometimes stalling sometimes picking back up and running normal. When it does stall it will start right back up immediately and run fine. I have not been able to re-create the issue, the truck will idle all day long never stumbling once. It just happens when driving. I've checked the TPS and it seems to check out and I've also cleaned the IAC valve. Not throwing any codes so I thought I would throw it out there and see if anyone had any ideas. Thanks in advance for any help.
