balls thought i fixed this the other week (car hunting on low coasting speeds before coming to a stop where it will idle fine, does it hot and cold)
got a new coolant temp sensor, had new amp coil and ignition pack and it seemed to have sorted it but now its back again :(
jsut doing a tb clean but tbh the throttlebody looks to not be that dirty, jsut going around and checking the pcv system hoses and non as far as i can see have splits in them, though the pcv valve seems to be covered in oil on the outside (right hand side of the engine as your looking into the bay)
guessing these jsut get full of oil and gunge up? (honda ones used to do this and give an iffy idle until they were blaseted out with carb cleaner)
any other ideas?

tb clean done
car idles now at 1500rpm for few seconds then drops down to 800 rpm idle and no hunting, fingers crossed once the ecu sorts it self out it wont hunt anymore lol

it won't, the ECU needs to find the tickover point so the revs play about for a bit. Mine did the same
