A thought - your TPS may be set too low, so that it thinks it's in open loop mode while the throttle is partially open? Might be worth a check to see that it's set to zero at idle but starts to increase the value (on startrek) as soon as the throttle starts to move. Your mention of 3% for 2000rpm is not impossible but I would have thought a little higher would be more likely.
Startrek says 0 degrees at idle - as pic above says
Startrek says 3% at 2200 rpm
I will plug back in though and check startrek shows movement immediately I move the throttle
Thanks barnacle for the very in depth help, I wish I understood more
Exhaust leak before the lambda sensor can cause bad emissions readings.
The picture on the right (bottom of 1st page) has hose clamp missing from oil breather hose also the hose is taped up further down so may be leaking at either point.
The tape was removed repaired and taped up again tighter for asthestics
The missing hose clip replaced too
As the more recent pic shows on the left
An exhaust leak ahead of the lambda is possible I suppose as the flexy section looks like it’s missing mesh, I can certainly see the spring looking bit inside.
Wish I knew if it was actually leaking here, I can’t hear anything. Maybe I will jack have to jack it up and feel around.
Thanks GrahamL too
Hey MM this is a learning experience isn’t it
