Starting new thread with updates and everything compiled.
Background:
Car ran great for over a year, averaged 21-22mpg.
Last Sept water pump blew and the car was running at 110C for a few days while I tried to diagnose what was happening, never overheated though.
MPG dropped to 12-13avg and power SUCKS. I would guess a 50% drop in power. Its just lifeless.
Parts Replaced / Tests done
- Plugs/Wires/Rotor/Cap <--- done last year brand new
- Compression Test GOOD -- average 180psi all cylinders, variance no greater than 5%
- New fuel pumps, fuel filter, fuel tank strainer, fuel tank inspected, all fuel hoses replaced
- Fuel Distributor + EHA brand new
- O2 sensor new
- Injectors are brand new + also checked spray pattern
- Coil swapped with spare
- Car goes into closed-loop. Duty cycle 55% and fluctuating
- Fuel pumps now gets 1L in 30secs (spec is 1L in 40secs)
- Fuel Pressures are 5.1/5.5 bar -- pressure holds @ 3.1bar. So pressures + holding pressure GOOD.
Ideas where to look now?
