AE111 running too rich - Toyota Nation Forum : Toyota Car and Truck Forums

Hey guys, this is the first time that I'm posting.(Have been a member for a while now)
My car started smoking and I took it to the local reconditioning centre. The mechanic informed me that the smoke was'nt oil burning but I was running way too rich. Next I went to the local Toyota dealership.They confirmed that I'm running way too rich. The technition said he tested the O2, Map, knock- sensors, but didnt find anything wrong. I then inquired whether they could change the a/f ratio. They said that it is pre-programmed into the ECU and that it can't be adjusted.

Next I went to the local tuning shop where they informed me to fit a unichip. I took the car in and heard back from them (+- 2 days later) that my ECU isnnt suited for a unichip(It resets itself).

What now?

Have you checked the Fuel Pressure Regulator and injectors? They may be putting too much fuel in and the ECU isnt picking it up...

Will I be able to check these myself (how?), or would i have to take the car in?

The fuel pressure regulator appears to be dented on top..?

Dont worry about the dents... I think they all have that for some reason

Checking the injectors is a matter of checking the resistance, and the pressure regulator is putting a guage on the other end. Getting the figures for both is a different story. Maybe someone can help me out?
