hiya guys can you lot help me sort some probs with my 92kreg 4by first central locking will work on drivers door but double locks on passengers door eg locks then unlocks with 1 turn of key changed motor any idears also surging to 3thousand when hot and surging about 15 hundred rpm when cold don`t do it all the time i know a little about cars but not enough canyou guys help me out ? also all new springs,shocks torx brakes and pads trackrod ends and bottom arms still got a knocking noise on lock drive shafts checked and ok only knocks once also poly bushed alround help me please i`ve run out of idears

 

on the central locking problem: check the wiring where it goes from the door to the shell. if i remember right its a single brown wire that tells the other doors what to do and if this is earthing on the chassis or crossing onto another wire it will mess things up.

on the knocking noise: (sounds stupid i know but worth a try) is the centre nut on the shafts at the correct tension? its just that you say it only knocks once which makes me think this.

hope this helps.

 

thanx dan will have a look into them but had both front sets driveshaft gaters changed so shafts should be tight but will check anyway do you no what mite be causeing the surging when hot or cold it only seams to do it now and again?? does anyone else out there have any idears its starting to do my head in

 

hello mate
i had a similar prob with my central locking, i turned out to be the wiring loom in the door its self, i replaced the the loom with one for a brakers yard and its been ok since.
i have got poly bushes on my car and it makes slight knocking noises sometime on lock i have put it down to the bushes as it didn't do it befor i fitted them.
hope this helps

 

Hi mate, re the revs surging, worse when hot. Had this happen just about a week ago on my 4b, was dirty sensor connections of the 5th injector, the cold start injector. First off I took the car to my mechanic, who disconnected the 5th injector, said it wasn't really needed, would make it run a little rough when cold maybe, but after this the car would sometimes stall and refuse to start (was flooding), called the RAC and got lucky, the RAC man had an old RS2000 with a Cosworth block in it so he knew his stuff, he figured that the 5th injector sensor plug just needed a clean and he could reconnect it with no problem. And all was well without me spending anything

 

thanx grave digger will check when im a bit better just came out of hospital after haveing an op thanx gezza hope it works

 

Had a similar problem c/locking wise myself turned out to be the relay playin up also if you've got an aftermarket alarm thats playin up that could be it,but i'd have my money on the c/locking motor itself on whichever side is playing up being faulty very common fault on most fords god bless henry!!

 

Have you checked and cleaned the Engine Idle Speed Control Valve? This has packed in on mine, i must renew it soon...DOH! The car has No cold start, sits at 700-800rpm when cold then jacks up to 3000 when warmed! Easy to replace, just 2 screws even i can do that LOL

 

thanx dooerevo1 i`ve had a new alarm fitted and change motor for 1 that works ok where is the relay at not checked that yet done every think else i can think of

 

thanx manxlad have tryed that already still doing the same as b4 will keep tryin till i get it right i`m like a dog with a bone when i get a problem i keep at it till it works

 

Now your testing my memory,what i normally do is ring or visit your main agent and they'll point you in the right direction on the microfesh or PC whichever they've got,sometimes they'll tell you over the phone.If i remember i'll give you a PM.

 

all prob`s sorted thanx to all that put me on the right path cheer`s till the next problem turn`s up may the boost be with you all

 

What were the probs in the end m8???????
My central locking has a wobbler sometimes

 

some of you are confusing the Idle Speed Control Valve with a 5th injector. can you see a fuel connection to it? no. it's just a valve that opens to allow more air to bypass the 'closed' throttle plate when needed.

 

i no a lad who had problems his cozzy kept backin off at so many revs even with no boost it turned out to be an air leek in the dump valve the diaphram was nackered. but tht was tempremental to it only backed of sometimes.

 

hiya guys and girls the problem`s have been sorted i.e the surging was a knacked idle speed control valve,the central locking was buggered wireing loom in the door in the end after changing everything else and the knock on the front turn out to be the anti roll bar lower arm bush was`nt tight enough only 1 pound of torque sounds stupid i know but it worked on mine thanx again for all the suggestion thay did help in tracking down the problems in the end
