2.0R

Left batt disconnected, still throwing several codes related to throttle position, threw on a second hand throttle body and all good now.
I was told by several peops on FB suby that I forked the TB by manually opening it.

main problem was would b=not rev past 3k and tried test drive and WOT barley gave me enough gas to move the car.

Yeah, can or spray into the inlet manifold, blew some shit... still not sure if it was the contents of the can burning or any actual shit it may have dislodged from the engine...

Nice.  A put in petrol UEC wouldn't feedback from the injectors to the air system prior to the injectors.  I presume you bought the manually spray into the air system stuff?

Wellll... around the time of my last post I noticed it had been driving more betterer, to the point tonight I noticed the CEL had gone.
There is still a slight flat spot but , probably nothing a set of plugs wouldn't fix.

Things Ive done to fix it;
 

Upper cylinder cleaner, which probably got into the secondary air system, causing two of the codes???

Gone back to my cheap premium fuel

Drove it

Ignored it.
 

Cost, around $20 on a can.

Had a bluetooth fall in my lap...

 

Try the switch on the brake pedal.
