Fuel system running rich?

[Rednaz]

Hi Guys!

I haven't posted in while but I've been keeping tabs on some topics on here. I'm unashamed to have taken this long to turn to my fellow brethen about this issue that I've been dealing with for the past 2 years which comes and goes.

The car died late year mysteriously on my way to work and wouldn't crank even and an auto electrician troubleshooted it and was adamant that it was the fuel pump solenoid (which my gut highly disagrees with but he wouldn't listen to reason) and he CLEANED ALL THE SENSORS IN THE ENGINE BAY (which I feel is a warm lead to the issue).

After he returned the car it was driving normal for about 2 weeks and then the problems started to slowly return to where it is again as bad as below described.

My car (2NZ engine) has the following symptoms again like 2 years ago:

- Loss of power under acceleration randomly and the car will jerk with exhaust pops and smells of fuel
- Sometimes total loss of power in first gear. When putting it in neutral and revving it has a burbling noise that stays under 2000 rpms (like the engine is flooded with fuel) (I've got a video of this, if someone can show me how to upload it to show you guys, please do share how)
- shifting between gears has a jerky feeling and feels like you've hit "an invisible wall" as you start accelerating in the next gear.

So far the following has been checked:
- Fuel injectors tested - 100% okay
- Fuel sending unit replaced
- Fuel pump solenoid replaced twice (once by myself and once by an auto electrician)

My gut is screaming the following: A something is falsely signaling the car that more air is needed and the car compensates with the fuel.

Please help guys, I don't want this dying on me again randomly.

Apologies in advance if this topic has been covered in a different thread : )

TIA
