Restarting this thread, for information & interest of others.
It appears I purchased this Ute from mofo 2 months ago; fully aware it still has some faults. Slowly trying to solve them on weekends.
The main fault is the transmission is still in Failsafe mode (for another post) and minor issue is the engine still surges slightly above 2500rpm +/-100rpm, noticed bit of a pulsing feeling when driving, in engineering we’d call it “hunting”, can’t find a stable rpm.
I checked the computer, no ecu faults.
The computer showed mass flow and rpm were out of sync, strange.
Checked & cleaned the mass flow, no different.
Blanked ERG, no difference.
Disassembled foot pedal and cleaned contacts, in case signal fluctuations, no difference.
In frustration I thought, since it had a new turbo installed, maybe someone stuffed up, removed vacuum hose off turbo (boost valve) actuator. FIXED IT INSTANTLY.
So, realised that hose must have been installed on wrong output of the vacuum control solenoid down near AC compressor and swapped the hose, engine RPM now runs perfect.
So, while still not fixing the limp/failsafe issue with transmission, I’m disappointed in whoever installed turbo and happy I resolved one of the faults.
Will post on other forum re transmission, need ideas.
