Torque Converter slipping a little too much?  At those speeds, the Transmission should select 1st and you should expect a lively take-off.

Sports Mode makes no difference to WOT acceleration.

Depends on the s/w version - some, even at WOT, change up too early

Hi boys.

Just got back from holidays in Heacham. . . . . Omega paradise it seems. . . . Saw six or seven not inc. mine lol

Anyways.

I can't pin point it. It seems like sometimes when I floor it from sedately driving it kicks down and I get a surge u p to the red line. Other times it will just rev progressively but when it gets to about four k rpm it picks up.

I checked the multirams after the journey. Front one opens with a good hard blip of the throttle. Rear one I can't see working at all.

And while I am here . . . Is it possible you can plug the rear multiram connector the wrong way round?

Only if you're a complete klutz and force it

Lol no, no forcing. .  Just a nice click when it went home.

Will get another good look to see if that rear multiram is operating. I know it operates at low revs like around one k. Then it operates at very high revs. Any idea what I need to get engine to rev to before this operates at the top end of grad revs?

Have a read of THIS and report back...

Thanks Al, helpful as ever!

4100 rpm and they both activate. Will do a more thorough check in a few.

Am I to assume though that I would have the check engine light on if there was a problem (based on marks thread?

Depends how broken it is... if the wiring is intact, then the ecu knows no different, ergo no light

Thanks mate. Will check and update later on.

Rear one is very hard to activate by revving, ya gota give it loads. Beyond any mechanical sympathy. Or tech 2 to test.


Might there be a vac leak somewhere?

Thanks Chris.

Thinking as long as it's warm it should be ok? 

I've gone round the whole engine with carb cleaner but not the multi ram piping. I'm thinking, after looking at marks vac pipe diagram, that I should look at all those connections and also the vac tanks?

Ime a vac leak needs to be quite bad for enough crab cleaner to get in. ...and what might draw in air at 4k or so, may not do so at tickover. A physical inspection, and wite often a wiggle in conjunction with the mk1 ear 'ole for hissing and changes in rpm often give results. Squeazing rubber vac pipes, and feeling your way along the plastic ones etc


Often, vac leaks aren't visible, as what's rubbed through is in the way of the hole it created. As it would... So to speak. Often the rubber joins in the 4mm plastic pipe split down one side or one way valves fail.

It does sound like inconsistent vac feed to me. Causing sluggish multi ram operation and loss of torque. So you press harder on the throttle, to the point it kicks down.

Is fuel economy high?

[Webby the Bear]

Thanks Chris. Fuel economy on the run seemed ok although I haven't checked it exactly. . . Half a tank for 170 miles. Roughly.

I'll do a physical inspection.

Wondering if at some point the thin multi ram lines have got muddled up. Then again, strange it's only recently seemed lacking in power

[Webby the Bear]

Chris, just been searching the site for more posts and experiences on this multiple ram issue.

I noticed a post from you that said when you turn the engine off there is a fading hiss for a second or two. . . . . . Definitely got this!!!!! Always had it in fact.  . . .
