V8 over heating

<< < (3/6) > >>

Skibum346:
From memory, we had a problem with lambda sensors on our 3.9 that caused the revving problem. The se4nsors were shot and were passing dodgy info back to the ECM. It as a result, was weakening the mix, then trying to recover the resulting stall... produced a symptom very similar to your description.

Might be worthwhile getting it in for a diagnostic. My local garage does it for £40... at least it would give you a better idea of what to chase.

Good luck.

with the revs flying up and down then overheating it does sound like a sensor or ecu fault rather than just a cooling system problem, ive got to speak to my local landy specialist in the next day or too ill ask them what they think..

cheers suggs if you could do that, then that will be great!!!!!

i no the revs went up and down then it overheated, but i think that its more of its getting to hot thats upsetting the fueling or a sensor....

.... but im not 100% on that..... it just doesnt make sence????

by any chance do you think that it may be an oil starvation thats making the engine run hot, as it would be metal on metal, and thats y it takes a while for it to over heat?????


im just coming up with anything no as im well confused

if anyone else wants to give me some info then your more than welcome

cheers

If you think it's the lamdas, disconnect them and change the tune select resistor to tell the ecu there are no lamdas fitted.
