Here are the symptoms - in no particular order:

1) Still got a kickdown problem

Sometimes when I boot it, it just WONT kick down - others the reaction is delayed, and sometimes it's OK!

2) sometimes at idle, it seems to "miss" a beat - and sometimes after it's been idling for a few mins, you put your foot down to move off, and it misfires for just a second, before then pulling away fine

Plugs and DIS are new, leads are fine.

No fault lights.

I am aware I need a new vacc tank for decent multiram operation - but it stilll feels overly sluggish.

3200 miles have elapsed since top end rebuild.


Thoughts welcome

have you checked for air leaks?

[Bionic]

First question has to be 'are the vacuum pipes connected where they should be and have not been misplaced on re-assembly? Second is 'are there any vacuum leaks at all? Even a small one is to big and one too many. In correct placement is an easy mistake to make seeing there are so many of them and they all need to be in their correct places to work correctly.
I colour coded all the ends and joints of mine with nail polishes.(No, before you all start I don't bleedin wear it either).

IIRC there's a kickdown switch on engines with a manual throttle. Might be worth making sure it's making contact on WOT.

Is that directly under the throttle, kev? - or attached to the cable somewhere?

All the Mig's I've taken apart, I've never come across this

No. Me neither. I recall it being under the scuttle panel where the cable emerges through the bulkhead. Not having one myself I've never needed to know.

Thanks Kev - I wil ldefinately investigate this

is the throttle cable slack on the throttle bodies?

all of ours have been too slack when we 1st got them, causing the car not to be able to rev quite to maximum, easily adjusted.

James .. if you have access to the "book of lies"   section 7B.6 Section 8 para 32...

 


Then Section 4A.3 section 3 .... 

[JamesV6CDX]

I do - but not for a while.... whatsit say?

7B.6 

Kickdown switch
32 The kickdown switch is an integral part of
the accelerator cable and cannot be renewed
separately. Refer to Chapter 4A for details of
accelerator cable removal and refitting.

4A

1 Working in the engine compartment, unclip
the inner cable retaining clip then slide the clip
out of the end fitting and release the cable
from the throttle cam (see illustration).
2 Free the accelerator outer cable from its
mounting bracket, taking care not to lose the
adjusting clip (see illustration). Work back
along the length of the cable, free it from any
retaining clips or ties, noting its correct
routing. On models with automatic
transmission it will be necessary to
disconnect the wiring from the kickdown
switch which is built into the cable.

Refitting
8 Feed the cable into position from the
engine compartment and seat the outer cable
grommet in the bulkhead.
9 From inside the vehicle, clip the inner cable
end fitting into position in the pedal end and
check to make sure the grommet is correctly
located in the bulkhead. Check that the cable
is securely retained, then refit the
heater/ventilation duct and undercover to the
facia.
10 From within the engine compartment,
ensure the outer cable is correctly seated in
the bulkhead, then work along the cable,
securing it in position with the retaining clips
and ties, and ensuring that the cable is
correctly routed. On models with automatic
transmission, reconnect the kickdown switch
wiring connector making sure the wiring is
correctly routed
