So, this time last year i bought a peugeot 306 automatic estate about 2 weeks later i discovered it had

over heating issues found i had a leaking radiator ---- had new radiator fitted

still no better so was running the car heater fan to keep the engine cool - heater blew

had new water pump fitted and new temp guage sensor ....

gears started being jerky but temp was staying down unless in heavy traffic then it was going up and then it would be jerky and over rev even in park. - had auto transimission fluid changed

list of issues :-

sometimes - but not always- jerky when stopped with engine revving all by itself

sometimes - but not always- the speedo doesnt work

sometimes - but not always- the petrol guage is all over the place

sometimes - but not always- forgets to change gear until the rev counter is at 3500

sometimes - but not always- doesnt change gear up a hill

runs terribly when the weather is hot - runs slightly better on non supermarket petrol ( have also put petrol cleaner in it)

also i have had it checked for head gasket and it isnt that and had a diagnostic on it and nothing comes up recently passed an MOT with flying colours except a headlight bulb !!

what can it be - driving it is stressful to say the least as i never know what its going to do next !! help :-D
