I don't have an O2 sensor on the car (checked the entire exhaust - it's original).

Even if the car had one and it was faulty, it would have been bypassed coz I have disconnected the EHA, but still mixture is too rich.

Leaned the mixture by 1/4 turn - still rich with EHA off.

Idle and running is good when cold but once engine gets warm, feels like it's flooding - rough lumpy idle and severe hesitation on acceleration.



Fuel pressure regulator is suspect - my old one was leaking fuel, and I swapped it out with a used one at the same time as my fuel distributor.

Maybe...

Need some help to check fuel pressure...
