Hi All
I can't seem to get the thing to run well for any length of time!
just changed a lambda sensor due to it failing and throwing up a code, the symptoms were stumbling at 2100rpms, now its changed it runs lovely up to 3100 revs then sort of feels like theres a momentary loss of power then the revs jump to 4500rpm then back to 3000 and carrys on untill I release the throttle,
Now this will happen on the move and stationary on both lpg and petrol and isn't giving any codes.
I've tested the TPS and the resistance is a smooth progression without any notchy bits if that makes sense.
I have spoken to the auto electrician who diagnosed the lambda and he said he thinks it could be a rev limiter fitted to the LPG system, but it will do it on both fuels confused
I cant get hold of the gas fitter to ask him so I thought i would let the PH collective have a pop
Over to you guys!
Cheers
