Westfield Zetec
« on: May 28, 2008, 23:57:17 PM »
I've been having misfiring problems with my Westfield 1.8 Zetec (Bog standard Ford 118bhp Injection,ECU, Cat etc). I took it for a diagnostics check and the only thing detected was that it was set up to run 91 Octane fuel. Apparentley on the Escort (which is how the diagnostics identified my car) there is a plug on the bulkhead somewhere which may or may not bridge two wires to switch the ECU to run for 91 or 95 Octane settings. I can't find this plug on the loom for my car. I am pretty sure that the loom was supplied with the engine etc from Ford Industrial Products as a new item when the car was built as a new car, hence the "52 reg" I think the high rev misfire I am suffering is probably down to the HT leads but would like to have the car running on 95 octane settings . Anyone have any info on this? The car is now running on NGK platinum TR5A-10s after seeing other reported problems

Can I ask what the gap on your spark plugs are?........only reason I ask is that my xr2i is running a 1.8 zetec and I`ve had huge problems with a high rev misfiring/cutting out randomly over the last few years and I`ve tried loads of things to cure it new leads,different plugs,different ecu`s with and without chips,new coil packs.

Finally found out afew weeks ago while just browsing a mondeo forum that the plug gap Haynes list in their manuals for the 1.6/1.8/2.0 zetecs (1.3mm) is wrong. Apparently ford changed it to 1.0mm after misfire problems.
Been as right as rain since I regapped the plugs.......no misfiring,pulls like a train and I`m getting alot better MPG too

Just a thought.

Cheers for that Lee but the clues in the plug number with the NGKs apparently. The original NGK plug was the PTR5A-13 where the 13 refers to the plug gap of 1.3mm the ones I have now fitted are the 10s with a plug gap of 1.0mm. The cars as sweet as a nut just running around but when you floor it in a higher gear it runs clean, stutters, runs clean etc from about 3 to 3.5 thousand RPM up to the redline. Afriend of mine races a Ginetta and hopefully if the weathers ok tomorrow night I'm going to borrow his HT leads and see if it runs ok with them. If it does I'll treat it to some magnecors but still need to sort out the 91 octane thing

Sounds more like a dirty MAF which is common, especially if you have an induction kit.  Clean the inside of the MAF out with carb cleaner, let it dry and try again.

A quick test is to unplug the MAF and go for a drive.  If the MAF is your problem it will go away with the MAF unplugged.



EDIT

The octane was part of the EDIS wiring.  To you internal or external EDIS?  I doubt Westfield would have messed this up any way.

Cheers for that Wardy I'll give that a try. As regards the EDIS, sorry I don't know what that means could you come back to me on that one. You don't know owt about  MSD coilpacks with CFM leads do you. I 'm thinking about buying some of those from their Florida home rather than over here as they're much cheaper.
Anyway thanks a lot.

EDIS is an ignition module used to trigger the coil pack, on early models this was a seperate module mounted on the inner wing or somewhere similar with a 10ish pin multiplug, on later models the EDIS module was removed and intergrated into the ecu so it was no longer present in the loom.

Do you know what year car and year the ecu came from? If so I can check a few wiring diagrams I have if you like and see what pin the octane adjustment is on.

Cheers Wardy I will have a good look over the next few days and come back to you.
This is so frustrating though. I am used to carbs and ignition, all these sensors and that, it's just not right, especially on something like a Westfield. Colin Chapman would be spinning in his grave! Once the car is right it's going for something lighter and simpler. I sold my old RS2000 Escort to part finance this (MK 2 X pack) Now there was a simple, focused moter.
Cheers mate anyway

Hi Wardy.
Just been for a run in the Westy with the Maf disconnected and at last managed to get it to rev out in first gear instead of just stumbling like it used to do. I t also seems to be revving cleaner in the higher gears as well so that seems to have diagnosed it. I'll have a go with the carb cleaner tomorrow night but the elements are very small and delicate so I'd better be careful. The Maf looks very clean but one of the springs is a slightly different clour to the other so hopefully a good clean will sort it.
As for the EDIS thing still not had chance to have a good look but will do over the next few days.
Thanks again Barry

Hi Christope.
I might have made a bit more sense of this problem now. I've taken the airbox off the car tonight so I could get to the remains of the harness. I found a few single plugs which might plug togethor. Looking through my Haynes Manual wiring diags I found that on the "typical SEFI fuel injection system post 1995 models" the octane boost link is shown as black and red onto white and black. I have matching plugs which fit are the right colour are next to each other on the harness and are on the same line as the MAF plug. Could this be the answer?
As for the ECU  I have it on the table in front of me. I have no idea about the year etc as I am the fourth owner but it appears to have part numbers on the Ford sticker. The top line says SME-105 OGRE EEC-IV  
and the bottom line says XS4F-12A650-LA followed by (in smaller letters) *DKDCH3CDJX7Y*
The plug going into it has 36 wires and the ECU itself hs 60 pins coming out of it.
I f you could make any sense of this I would be grateful.
Cheers
Barry

I always though the octane plugs were left disconnected for the higher setting (95 ron) and then plugged in to run the lower ron map.

I'll check mine tomorrow see what its like.

Hi Christophe.
I checked today with a guy at works 97 escort zetec and followed the wire down from the MAF plug to under the nearside inner wing and found the identical plugs plugged togethor. So going back in time mine were unplugged and on the diagnostics check it said 91 octane settings so now I've plugged them in and the car started ok. The big check should be over the weekend (if we get the weather). I've cleaned the Maf with carb cleaner and the 95 octane settings should release more HP( more ignition advance?) so we shall see.
More thanks for your help and I will let you know how it goes when I get the chance.
Cheers again.
Barry
