Got everything back together and engine is running rough. Poor idle, poor acceleration.
Throttle response is terrible. Just puttering off the line. This is the worst symptom.
Basically kind of puttering at idle. Especially when cold. Less so, but still noticeable when warm.
No smoke. I did get a faint sulfur smell on first start-up but that has since dissipated.
Past 2500 rpm its fairly smooth.
Fuel filter replaced in 2019 with less than 1000 miles. I added inline filters to the lines coming from the tanks. The fuel that was in the tanks looked perfectly clear. Injectors have been cleaned and tested by SD.
Here’s a couple videos where I’ve captured some of the symptoms in my garage.
Breather outlet looks unobstructed, but I will pull it off and clean the screen. I did get some oil seepage from the dipstick tube, so I thought this might be contributing.
I guess I need to investigate the ignition coil, distributor caps and rotor, spark plugs and wires, do a compression test and checking grounds.
