Andy 3i Posted February 10, 2013 Share Posted February 10, 2013 So I've finally got my escort back together and working somewhere near but a strange problem has occurred. I've put the wiring in like stu said, I've got the 130 maf, tps, idle air etc. but under full throttle it hesitates like mad. Light throttle is fine :/. Although part of me is thinking that I put the 1.8 injectors in rather than the 2.0 ones...how do you tell? Obviously it could easily be a wiring fault because I've played with it a lot to get it running but I'm just wondering if there is something that jumps out to anyone? It's got brand new gen ford plugs and leads...but a used coil pack which I'm led to believe worked because it came with the engine when I bought it off trig.

Stu Posted February 10, 2013 Share Posted February 10, 2013 Could be so many things chap! Did you sort out the shielded CPS wiring? Not usually related to load, but possibly engine speed. Link to comment Share on other sites More sharing options...
Andy 3i Posted February 10, 2013 Author Share Posted February 10, 2013 I know, it's baffling me. Yeah, I shielded the wire with some crank sensor wiring and it seemed to improve it slightly (or it's placebo) but the most worrying thing is that it was rebuilt 4 years ago and has just sat...never been run in and it's fcuked . I've got a spare coil pack which I could try just to eliminate that. How could I tell if I've mistakenly put the 1.8 injectors in? All I can tell you at the moment is that they're green which is probably of no help. Link to comment Share on other sites More sharing options...
Stu Posted February 10, 2013 Share Posted February 10, 2013 Injectors - you'd have to go by the part number, I don't have a list to hand but someone else might be able to confirm for you. You can't go by colour. Link to comment Share on other sites More sharing options...
Ahmotorsport Posted February 10, 2013 Share Posted February 10, 2013 Does it turn into a misfire under full load? Does it spit and pop and mess about or it just doesn't get up and go? Link to comment Share on other sites More sharing options...
Andy 3i Posted February 10, 2013 Author Share Posted February 10, 2013 I didn't think colours would be helpful to be honest...there's just something niggling in the back of my mind that I have stuck the wrong ones back in. It basically pops, bangs and has no get up and go under full load...but light throttle appears to be fine. I've only driven it around a private estate as its been off the road for around 4 and a half years . Link to comment Share on other sites More sharing options...
supersport Posted February 10, 2013 Share Posted February 10, 2013 double check the timing, as if it's half a tooth out it will run poorly. Link to comment Share on other sites More sharing options...

Now gently accelerate until full throttle, just gradually build the throttle, then let us know what happens. Link to comment Share on other sites More sharing options...
Stu Posted February 10, 2013 Share Posted February 10, 2013 Sounds to me like it's getting upset going from closed loop to open loop fuelling, which is often down to bad MAF, wrong injectors, potentially bad TPS, or perhaps a fuel pump/filter issue.. it's a fairly big list of possibilities.

Andy 3i Posted February 10, 2013 Author Share Posted February 10, 2013 I will try tomorrow and let you know how it goes . If has got a brand new gen 2.0 maf but probably a 20 year old tps. If the one off my 105 xr is compatible ill stick that on and see...I will compare part numbers and see . Filter wise...again brand new and pump I'd the old one from the 1.4 engine which delivers the same fuel pressure as far as I'm aware (I hope) because it would be a bugger to change it after I've already put a new tank on . Although...can't rule out any wiring faults really Link to comment Share on other sites More sharing options...

Andy 3i Posted February 10, 2013 Author Share Posted February 10, 2013 Admittedly they are about 4 and a half years which I know is old but the engine has hardly worked. Worth a change I suppose Link to comment Share on other sites More sharing options...
Ahmotorsport Posted February 10, 2013 Share Posted February 10, 2013 Wow lol. Yeah they need refreshing. Are they from the old engine? Link to comment Share on other sites More sharing options...
Andy 3i Posted February 11, 2013 Author Share Posted February 11, 2013 The old engine was a 1.4 . no, I put new plugs and leads on when I did the engine rebuild and it just sat for a long time. Ill have a look today and see how I get on . Thanks guys Link to comment Share on other sites More sharing options...

From previous experience, personally I would suspect the TPS sensor/wiring as first suspect. Link to comment Share on other sites More sharing options...
