Sounds flooded, floor the throttle and keep it turning.
Sometimes when the plugs get wet it travels through to the lambda prob. I've had to take it and the plugs out to dry off.
Difficult to get any good stuff at the mo and the chinky tubes will be thinking of falling apart before they've left the seller.
Pick up some silicone tubing.
Happy new year to all.
I went to bed at 10.30, watched tele till 2am till Mandi got in. She didn't want to go out either but was dragged out by the daughter.
