Not sure but should the Hall Sensor ie Cam Sensor be active with the engine running ?

These toggle rapidly between the two when running. Only really useful for static diagnosis.

Sounds to me like an ICV / sticking throttle body issue. If it's idling that high, the air is getting in somewhere, and, with the MAF reading quite high, it's not coming in through a leak.

Would this have anything to do with the backfire i'm getting at certain revs Kevin ?

I'm also going to blank off the MAP feed pipe later to see if I can isolate the LPG side from the petrol side.

Could scrubbing the throttle body with brake cleaner and a toothbrush have damaged it in some way ?
Anybody know what the resistance at the throttle pot should be with the body closed ?
The engine still has a 2.5 wiring loom on it so I had to leave the 2.5's throttle body on 

I'm away from the car at the mo so can't check till later

Turned the key for the first time in a few days this morning.
Started first turn of the key.
Took swmbo to work and the car ran great.
No popping or misfiring or anything even thought the revs are still high

Seriously confused now.

Can anybody shine any light on this ?

Throttle body removed from the plenum, left jammed open and sat in a sealed bucket of thinners over the weekend.
You could now eat your dinner of it.
Replaced the icv with another spare thanks to lincs rob 
Car now idles at around 600 and responds to the throttle better but it is still running very lumpy and popping / backfiring at certain revs.

Since i've been swapping and changing bits, is it worth resetting the block data to see if that smooths things out a little then take it from there ?


Edit:   just filled up with lpg and worked out the mpg.
I only got 12 mpg out of the last tank 
Normally get around 22

did you get a fix on this??
