Ok so I’ve been battling a low idle for awhile. Couldn’t really pinpoint why it starts tell recent.
It seems to start after going to 55mph+. It runs fine after ECU reset, driving through town for a few days. Jump on the highway and when getting off and coming to a stop (foot off the brakes or rolling to a stop) rpms drop to below 450 rpms. Then the issue is sticks around and is intermittent. Until another ecu reset. Also sometimes if I turn the truck off and back on the problem will stop for a bit.
TPS is good, IAC is good, MAF is good, new O2 sensors, new spark plugs/wires, new air filter, new intake hose, new fuel filter, throttle body was pretty clean but I did a quick wipe down. Hoses seem fine with vacuum test. I just don’t know.
Maybe a new distributor cap, maybe a better cleaning, maybe a vacuum leak. Those are all that I can think of now. I’m even thinking about replacing spark plugs and wires again.
I need help!!
