Title: Cossu not past test...
Post by NiceMan on Jan 15th, 2009, 5:47pm
I find next error code:

P1131 Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Lean - Bank No. 1
P1151 Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Lean - Bank No. 2

And Test Office say:

               Idle  / 2000->
HC           406  / 55
CO%       2.76 / 0,811
O2%         0,8 / 0.7
CO2% 13,06 / 14.2
Lambra            1,001

Where problem? Lambda not work? 1 year ago all 4 lambda sensor change to new but they are cheap one not orginal...
This need fix and some little other them i take stamb to paper and start use Car.

hi there

to me, i'd say your car was running rich because of an air/vac leak.

check all vac tubes and the pipework to the egr valve.

could also be a fuel pressure regulator issue.

you may have a vaccum leak  under throttle body or inlet manifold also tps sensor  can throw up all sorts
problems  i had tps problems car would start but cut out  for no reason when running  and at 50 mph  car would lose revs and threaten to stall got a replacement throttle body with tps attached  now car runs okay
does your car stall  then start again  okay

if you find  fuel pressure is okay  and still not start  check for spark at spark plugs check dis pack
