Engine Stumbles When Braking?

[swanny1970]

Hi All

 

Been having an ongoing problem for several months now with loss of power, kangarooing etc. Tried so many different things to resolve the problem, new coils, HT Leads, plugs, gaskets, checked hoses etc and all to no avail. Went to the scrap yard the other day and was amazed to see a Ford Scorpio, with exactly the same engine as mine. Needless to say, I have grabbed a load of parts as they are so hard to find. Got the MAF from the car as it had exactly the same part number as mine. Came home, tried it and the car ran a little better, but still has this problem where after about a minute of driving, the engine really struggles and then it is as if something has 'kicked in' and the car drives brilliantly, that is, until the ignition is switched off whereby it all starts again! I decided to attack the MAF with several screwdrivers to try and get the top off! Eventually managed it, cleaned it up, put it back on my car and WHOOOMPH! Loads of power, no pulling back, nothing making the engine stumble as it usually does. Now, as I was patting myself on the back, I tried braking, whilst in gear and the engine starts to stumble, as if it wants to stall, but not cut out. However, if the engine is in neutral when braking, this doesn't happen?? Could this be gearbox oil, lack of I mean? If not, any help would be greatly appreciated as always.

 

Kind regards,
