Hello everyone, I just got my first mustang and I’m having a few issues, it’s a 2000 v6 5 speed.
On a cold start it runs and drives great, but after it warms up it idles rough and actually died on me yesterday and didn’t want to restart, after letting it sit for a while it started fine and ran fine
The codes I’m getting are p0411 for the secondary air pump, as well as lean codes for both banks and a misfire on cylinder 4. It is definitely missing at idle when warm but not on a cold start and it usually smooths out at a higher rpm
Any idea what could be causing this? I get the idea from the research I’ve already done that the p0141 secondary air pump code might me a separate issue. Could a bad ignition coil cause these symptoms?
Any help is appreciated, thanks
