Hi, anyone recommend a good Indy near Manchester, England?
Also anyone know what the code P0781 is? Not seen this one before, have had a few P0171 and P0174 which seem to be a leaking vacuum hose and goes away for a few weeks then pops up again while driving slowly. Thought i had this fixed after i tightened up all hose connections as it disappeared for weeks. Think i will take car to an Indy now and get it sorted for good as its due a service shortly.

 

That's a transmission 1-2 shift malfunction code. Likely just needs a TCM reflash.

 

Check LTFTs using OBD live data. If you've an air leak find it soon as cats are at risk.

Make sure trans not low on oil.

 

Thanks for replies, there is some differences in live date LTFT 18.0 and 19.5 at idle, i will check the STFT tomorrow. Anyone know a good Indy in North West or Yorkshire?

 

Forget STFT. LTFT should be near 0 (say +-5%). Rev to say 2500 and if they head near 0 then you know it's a leak. As they're similar you'd be looking for a leak before the sides split going to the 2 banks.

 

You did not answer? Has the transmission been serviced at all? At least a fluid level check?
