fiatecuscan fault codes
i'm having ongoing probs with my 2002 147 2.0TS non selespeed. It started with a misfire and lumpy idle then the dreaded EOBD light and MCSV warning. I took it to an independant with a really good reputation, and they found oil in the spark plug wells and a knackered set of plugs (odd as they'd only been in for about 8000 miles) but they showed me and they were horrid (Bosch plugs too). The diagnostics showede 7 fault codes including coil 1 and 4 misfire, lambda sensors and some others. They replaced the plugs with NGK and tightened down the rocker cover and all was well for a day until the light came back on with the misfire. I went back and more oil was found in the same place so they replaced the rocker cover gasket. Problem gone until today and the lights on, the cars misfiring and hesitating intermittantly. I fitted a new top of the range Bosch battery as the car had the original on, but no change. I now have Fiatecuscan and the relevant lead and I'm getting the following 2 codes:
P0150 Lambda 2 signal above catal Invalid Signal
P0130 O2 Signal 1 Pre Cat No Signal
Granted 2 fault codes are better than 7!!! so I think I'm getting there. However do both these codes mean I need to replace both Lambda sensors (assuming I have only 2).
My ECU is an Me 7.3.1 if that helps at all.
Thanks for looking
actually I think I have 3 sensors, 2 in the downpipes and 1 underneath somewhere
