running issues giving me a headache

Right guys and girls am a bit confused as to what this issue could be. Basically my car has been running really rough, if I let off the accelerator pedal rather than flooring it, it will like backfire popping loads out the exhaust as though its over fueling or something? Ive tried unplugging the MAF and for awhile it will idle perfect and run perfect but if I leave it unplugged for say half a day or a day it will just run exactly the same whether its unplugged or not which is quite strange. I have changed the MAF for another second hand one that apprently worked perfect to see if it helps but it hasnt made any difference.

 

Any ideas guys its really starting to annoy me? :) Thanks all :cheers:

 

P.s. Another thing to note that I remembered the other day when I last serviced it 5000 miles ago, I didnt change the sparkplugs as I didnt have any, was just wondering whether this could be a contributing factor.

Do you really want to go the route of randomly replacing parts?

 

No of course not. Do you have a rough idea? Do escorts have an eobd port to plug into I have never looked to be honest :pancake:

 

 

as Stu indicated, offered solutions could be relentless in regards to part swapping.

 

but that said!

 

I have suffered similiar and it was down to my Lambda being fecked, that atleast is a easy one to check without requiring any mechanical work, simply unplug...you'll find the plug for it beneath the crossmember directly above the radiator and if your issues vanish you'll atleast know whos the culprit.

Tried what 'shawdreamer' said and replaced the lambda sensor with a brand new one and it has cured the problem! :D Yay can finally get back to enjoying driving it :D Thankyou mate :cheers:

 

 

suprising how often it go's unchecked when these symptoms crop up, probably due to them being identical to the ICV failure ones I suppose.

 

np anyway fella, glad to help :thumb:
