'Electronic Fault' warning light...

[ed_172_cup]

I was driving to get petrol earlier today, came to a roundabout and my car started to jump as if stalling when pulling away - it never cut out completely just wouldnt let me go above around 15mph without semi stalling and the electronic fault light coming on. i first thought was cos i was running on vapour and the car was coughing as the last remnants of fuel were being used.but the warning light for a fault was on... anyway managed to get to the petrol station, fill up and when i pulled away this time the same thing happened but also the exhaust fume warning light came on...!! so now that stays on all the time and the other light only comes on when you drive (it will idle and rev perfectly). anyone got any ideas before i take it down to the garage?

check the case around the ecu, if the metal vibrates it car damage the wires and cause this to happen

Need to get it on a computer see what the fault is, might be a faulty lambeda sesnor.

turns out it was the throttle potentiometer causing the fault - has anyone had this problem??

Yep there quite common problems

Not cheap either

New throttle bodies arn't cheap £150 or so at least I think.

They are around £250. The first thing to do is clean it out with some carb cleaner, oil from the breather tends to muck up the TPS built in the body. ive fixed loads by simply cleaning them up.

hi mate. yes i had the problem fixed - cost £50 for throttle potentiometer and lots for labour! however i have now had the car running for couple weeks and its doing the same thing again!!

tbf it sounds like the MAP sensor my old 1.2 did the same

 

[ed_172_cup]

thought maybe something to do with fitting induction kit - maybe crap is getting into the throttle housing?? altho my mate said his corsa did this before and he had to get a new ECU...

dunno mine was the MAP sensor on a completely standard engine. £30 to replace problem solved

problem solved! got a OBD2 diagnostic tool other day, plugged it into the car and cleared the fault and now shes running fine! it was like the car was in a safe mode or something!...
