hi all ......i brought my pulsar 2 moths ago (its been sitting out side waiting for a mot )i had a cat back strait through exhausts with the car because the one on the car was rotten .i had it fitted and the lad who fitted it told me that the lambda censer was no good as it was damaged bad dew to rust so when the new exhaust when on he cut the lambda censer off .i took it for a mot and it failed on the c02 emissions 7.14:shock:
the 1st thing i did was look at the spark plugs and found that 2 of them were loose and 1 of the leads wasn't attach properly so i put on a new set of spark plugs ngk pfr7b took the car for a long blast up the motorway went back to the mot garage to test the emissions again they read 6.39 and on the way home the car felt under powered iv ordered a lambda censer i'm hoping will cure the problem can anyone shed some light on this.............................. ps the plugs that were on the car were aga iridium k9rtci

Was the sensor that was wrotten in the cat? If so thats not a lambda sensor, it's a temp sensor, and many cars run fine without it.

Tbh there's gonna be an underlying prob to the running rich problem and i'd start by looking for air/vacuum leaks.

Also do a fault code check and consider re-earthing the maf as it tends to give problems even when the fault code shows nothing.

Without wanting to hijack the thread what's the purpose of the car knowing the temperature at the cat?

I ask because I cant get the flipping thing out my de-cat pipe and the connector won't fit through the hole in the floor and I'm getting very close to chopping the bugger off.
