Exhaust Welded

Had to have my exhaust welded today just before the pipe went on to the manifold, after picking her up she was great until 5 miles down the road the Engine Management Light came on (never happened before) could this be a problem with the lambda sensors I know they said they had probs getting two off!

4.0 V8 Discos have four Lambda sensors I think.
Check they have plugged the leads in properly from the Lambda sensor to the loom.
The little plastic connectors can be a little difficult to locate when reconnecting so one could have just popped off, the ECU will lose the signal and therefore show a fault.
I hope the garage wasn't too heavy handed in removing them from the pipe and damaged them, that could also be a possibility.
Hope this helps.

thanks boomer will do

cheers

Have a look at this link if you require new sensors only two are required. RichCatalog
