> Had this same issue when I installed a chipped ecu on my car. Ended up being a faulty o2 sensor. In my case the ecu ran fine with the 02 unplugged but like shit with the ecu plugged in. So check your O2 sensor

see this makes more sense to me then the cap and rotor thing…

car runs normal on a cold start until its warmed up…which goes from open loop, too closed…open loop doesnt run off o2’s, where closed does.

I might try to unplug my o2’s today and see what turns out.
