Hi guys, bit new to the forum but just bought myself a 2000 mk3 2.0 mondeo. Its got a bit of a running issue. Any help would be great.
Basically the issue is it starts and drives but seems to struggle and judder at low revs then when you slow down it drops its revs then stalls. Its got me a bit baffled. Ive just serviced it, including ht leads and fuel filter.

  • You can try new spark plugs, cleaning the carb, injectors, air filter (incase its an air intake problem), maf sensor, other than that i can only think its the coil pack maybe. A ford code reader could help you confirm the fault. Hope this helps.

Hi it is the same warm and cold, although it does seem to accelerate over 4000rpm, but struggles to be driven normally. Ive already changed the plugs, I was thinking of cleaning the throttle body and idle control in morning. I will look into getting a code reader. Although would the battery cause a fault, as my on screen test showed 9318 low battery volt.

I wouldnt have thought so possible though i suppose. See how you get on with the throttle body/idle control. The MAF sensor could be sooted up and can cause a problem with low revs and stalling, you could trycleaning that aswel just be careful with it as they arent cheap and theyre delicate.

Hi Dan, so today I cleaned out the throttle body and idle control valve and also replaced the coil pack, and still hasnt cured the fault. Im now wondering if its a fuel issue, took it for a spin today and it really didnt like it. Doesnt sound like its missing but hesitates and judders under acceleration. It doesnt like going up hills. It is also using far too much fuel.

Ok, Ill look at them, although that was next on my list when I change the inlet manifold to do the injectors to be on the safe side.

Hi Dan, so Ive been busy taking car apart, Im in the process of digging out a working second hand fuel rail with injectors, whilst that is of im also trying to dismantle the inlet manifold as it has the rattle, and tough I maight change egr valve whilst engine bay is empty. If all this doesnt work i will be lost. Ill update next week once the car is back together.
