hi. its an 00y 156 sportswagoon 1.8l.
i had an airbag issue so i set my self up with software and cables. no bother, airbag light gone. then i browse trough the engine and notised that
1- oxigen sensor, shows cold, even engine is hot, then an odd time it shows rich then lean then cold again.
2- air temp sensor is showing about 40c even is 20c outside. i dont know where its located, maybe on car being static it shows more from engine heat.
3- termostat; tempreture waries from about 80c up to times almost 100c. when air con is on, it does not creep up that high, when aircon isnt on and im sitting in traffic, temp raises up to near 100C and only then fan kicks in. when im driving along motorway, temp is around 80c. think its termostat or cloged radiator??
4- car isnt going right at all. well its smooth and nice to drive but very low powered. once the rpmn hit about 2.5k rpm it does pick up the speed nicely up to about 3.5k revs then again like nife cut. it even picks up speed faster with 5th gear on from 2.5k - 3.5k rpm than 4th gear on higher rpm than 3.5k
ps. shes grand on emitions, as im just after passing road test. so shes not overfueling
