No error codes, but it does seem a little slow off the line.

I'm thinking could be breathers or throttle body, failing that running too cold.

Wouldnt always give a code if the rams werent working. Mine didnt work and had no light come on. It might just be worth checking.

Similar - very little difference.

The power drop feels like a very hot summers day.

DBW are a bugger to check - I'll have a look at dinner time - only the rear one moves without a load doesn't it

97000
Crank about 3 months ago
very little difference
Normally I get on acceleration around
7.8 petrol, 9.0 gas
now getting 9-9.5 on both.

It has had an Italian tune up

It is due an oil change (early not 10,000 miles)

Plugs are good, coil packs seem OK.

I will check the exhaust at the weekend

The weight of that bloody great fart juice container in boot.

Seriously, check for vac at multirams.  Hope its not throttle body beginning to fail, crappy DBW things...

assuming a healthy car and blocked egr only can be lambda sensors becoming old or cats..(mine was)

ps : although not logical I see cars used in LPG for a long period have drop in fuel performance also even with seperate ECU.
Can be related to LPG subject.

Front ram - my piece of wire wobbles when floored, so it works.

Can't even see rear ram - except for a bit of pipe.

On overrun it sounds like a bit of fuel is getting through as it pops a little.

Sounds like a manifold is blowing when cold :(

Suspect exhaust leak too
