Low on Power

2.9 12v Auto
Just seems to lack Power when accelerating
auto box seems to work ok - not slipping
cruises effortless at motorway speeds
just doesn't accelerate that quickly from any speed (even after kickdown)
it has just passed a MOT & all the Emissions were fine
I also have a old mk3 Granada 2.9 Manual
which pulls away a LOT better even in top gear you can feel it accelerate
Any Ideas ?
Does it just need a good service ? bits replacing ? bits cleaning ?
Thanks Martin

hi there
could be a fuel pressure issue; we're seeing more of that now. have you checked all the usual things? spark plugs, correct grade of oil, etc.
don't really know much about the 12v.

Correct grade of oil ? - engine or gearbox ?

Hi mate, im having exactly the same problem myself, although i also have a slight idling problem when the car is stationary but waiting to go in drive, chech your vacum pipes and EGR valve, seems to be one of the biggest suggestions on here for the problem. I replaced the plugs, HT leads, coil and it made no differance at all. Good luck and let me know how you get on

Hi martin, the result altho im still not sure is that the fuel injectors need replacing or re conning. He said he did a scorp a few weeks ago with exactly the same problem and it solved it

I wonder if this is your problem with the car?
ALL the 12v have a Distributor Cap. 6 Leads and a Coil Lead. The coil is down on the right hand side of the engine bay looking into the bonnet from the front of the car.
I wonder if your car has been modified and your ignition system is non standard.
Only a thought.
Also, it's not a good idea to remove the canister that surrounds the dizzy cap. Apart from protecting the cap, it also provides shielding from moisture and water a bit like the battery cover.
As for acceleration, the 12v isn't a Cosworth, but even so, it will out accelerate most cars without any effort from standstill. If it doesn't, then yes, you have some tuning issues.

If its that down on power check to see if the cat has broken up and is blocking the exhaust. THAT could cause all of the syptoms that you describe, even though the car runs OK.

How do I tell
Would it still have good emissions if the Cat is US ?
(passed it's test easily)
if it is the Cat do I have to replace it
can I just clean it out - so it's straight through
or just do away with it altogether
I know on my Bike it's so much better without it
Thanks
Martin
