Which sensor is at fault?

[Savi]

Hi guys,

I think its the Lambda sensor, but not too sure. Been running a Mk1 clio with a F4R engine (172) and theres been a number of problems. The main one is when i'm cruising in 5th usually, it cuts out (no power, but engine still running) i press the throttle a couple times then comes back to life. It happens in 2nd, 3rd and 4th too, but always seems to happen when cruising around 60+ in 5th.

The car is running a decat, with both lambda sensor's plugged in still.

Would appreciate any help, cheers guys

you need to get the OBD2 port wired in. HAve a word with Matteh, he's done it on his mk1, it's not many wires. Easy to see what the sensors are ding then
