1999 Auto V70 Engine Runs Like a Pile of Rocks

[Pozzouk]

Evening all, I have an 1999 Auto V70 XT Engine Model B5244S2 i've had the car 5 years and from day one she always wanted to gag and jump forward with the foot-brake on - Volvo told me they could not identify the fault - that was the last they saw of my cash.

Then about 12 months ago i found that i could drive without a problem 60 miles down the motorway but that now and again the first roundabout or hold up the car came to the engine would deteriorate to such an extent it was as if all five pistons were fireing in some sort of random chaos!

It was suggested that it was the ETM - I gave it a good spray clean and all seemed well for a week or two but i think it was just a coincidal improvement.

It now seems that as soon as the temperature comes upto the 3 Oclock position and the car comes to a stop at lights or a junction it goes lumpy and the revs become slightly erattic.

So seeing as it seemed as though it was an overheating issue i checked the thermostat, the temp sender unit, fan and relay all seemed to work except the fan never seemed to run unless the sender unit was disconnected - this makes the fan run constantly and keeps everything cool but although never going into major lumpy mode presumably coz it doesn't reach high enough temperature it is obviously not that happy when first setting off.

Sorry about the essay but hopefully one of you guys might be able to point me in the right direction.

Please Please Help!
