306 problem

schoolsout · 03-09-2011, 04:14 PM

hi everyone, its me again with a problem with my 306 1.9 diesel.
when the engine is cold i have no problem with it, but when the engine warms up the car seems to hold back when setting of from a junction, only way i can describe it is this,, it feels like a petrol engine with a flat spot on the carb, the car kinda holds back back when changing gear or setting off, if i floor the gas it dont seem to do it, any help would be great on this guys

When is the last time it was serviced?

hi m8, i have no idea when it was last serviced, i only bought it about a week ago

maybe it just needs new filters and an oil change. Is it idling ok?

Not sure where it is, but look into the EGR valve - these should only work when the engine is warm, and should close-off when idling, pulling off, and accelerating hard.... sounds possibly feasible to me. On the other hand, haven't a clue where it is on the 306 I'm afraid

I'm not sure, but I think his is non-turbo. He's never mentioned turbo.

Is the EGR valve on the pre HDI models? Another "thought" is that I'm near positive that the 1.9 diesel engines aren't HDI.

By all means everything I said there could be wrong.

EGR valves appear to have been fitted to dozens of cars for many years. I maybe wrong, but I think nearly all modern diesels have them, petrols can have them too. Not wanting to promote other sites, but http://www.wanapart.co.uk/product_in...aign=fuelparts shows the EGR valve for the 1.9D

Nice one. From what I remember, filters are cheap, and easy to do.

Make sure you change the oil or there's no point in changing the filter
