mondeo running problem
Discussion
hi,can anyone help! just bought a mondeo 2001 2ltr petrol the car holds back cuts out under load, only way to keep it running is a very light throttle only fault code is lambda circuit has had new sensors fuel pump and ecu check sometimes it is fine anyone else had a problem? any help would be great,thanx.
Just a "for what it's worth".
Whilst waiting for my MoT, the garage manager was talking to another customer about reading error codes. It seems that air flow meters and temperature sensors rarely, if ever, give logged errors. Maybe this was just one particular model (not sure what) but his logic was sound. Basically, because both the AFM and temp sensor have a naturally wide range, it was difficult to to detect anything out of the ordinary.

Problems with current vehichles can't always be determind by pulling codes, it sometimes takes a tech who knows how to read PIDs (parameter idenification data) and/ or freeze frame data. Codes rarely get you to the root of the issue. Whilst waiting for my MoT, the garage manager was talking to another customer about reading error codes.

Sometimes air and temp sensors are easy to call the fault because they have built in defaults, if you moniter the ECT_ PID with a cold engine, then drive the vehicle for 20 miles and it never moves from -40F, you can be sure there is a problem with the sensor or it's electrical circuit.

Sounds like your issue may be with the throttle body or throttle position sensor to me, but I'm just a lowly Ford mechanic...
If you aren't getting any pertinent codes it could be a base engine problem as well, have someone with Ford IDS or equivalent run a power balance and compression test, head gasket blown? if you keep getting O2 (lambda sensor) codes check for exhaust leaks, before or between the sensors. A partially blown head gasket letting coolant into the exhaust will kill lambda sensors right quick.
