can anyone help??, just bought a 96 rs2000 4x4 as a project, which now seems like it's turning into a nightmare to be honest, car drives fine, but has erratic tick-over and sometimes will stall, changed lambda sensors, idle control vale, had codes read all clear, and reset to manufacturers settings, removed the pipe work from manifold etc., cant find any air leaks, it's getting to the stage where im going to twat the bitch with a hammer.

or does anyone know of a carb conversion set up for sale??

thanks terry

 

My mate had this on his 2wd rs2000 and it turned out to be the seals on the injectors. We changed them all re-set the ecu and after a quick drive it settled its self down and been fine since

 

checked the throttle body and TPS, maybe even the idle control valve, crank sensor

 

I'll have a look tomorrow, any idea where to get new seals, i believe fords don't sell them anymore?

t/body checked and cleaned, tps seems to be working ok im told, fitted new idle valve,

i may now have sourced a bike carb set up, but will check crank sensor tomorrow, thanks

Has the battery been changed or unplugged recently? if so did the ECU relearn the engine?

To do this unplug battery over night reconnect then start the engine. THEN JUST LEAVE to idle for about 5 mins without any interference or turning off! -Job done

see if this helps!

 

tried that Brendan, just as you said about battery, from cold it starts first turn, fast idle around 1200rpm, after a minute or so it will drop to 900-1000 rpm, and is ticking over fine for about 30 sec, then revs are up and down 500-1500 and it will stay like that for as long as you like.

my mk5 rs2000 had this problem and it turned out to be the injector seals.they get all out of shape like this


i went to B&Q got a box of o-rings found 4 the same diameter but not the same thickness and just doubled them up job done,that was 5 years ago and still going strong

If you find it's the injector seals you can also try scuba outlets for seals. Some of them will also sell Viton rubber too. Scuba seals are good way past most pressures you need in a car! 230 bar or 3500 psi is normal!

 

i removed the seals this afternoon, and they are just like rs Gary's picture, knackered, I'll fit new "O" rings tomorrow and see how it goes, i have found a diving outlet near me, so I'll try them first then back to b&q, thanks for your help

Renewed injector seals today, and the bitch is still playing up, had enough now, bike carbs going on, well in a couple of weeks after holiday, if it wasn't so clean I would scrap it poxy motor.
