Been having a few problems with MPG and a flat spot and occasionally getting a little too much exhaust fumes, very wet at that giving me the impression of too much water in there. At the same time it smelt like it was running too rich*. The flat spot I experience is when first engaging the clutch and doesn't matter if the engine is warm or cold. (Although can run slightly better on cold with choke being open I guess - depending on temp outside).
Since then I've been told the timing was out and as a result told it was corrected - BUT still I have the same problem.
I've been looking at various threads on problems that others have had and think some sound very similar, and not, at the same time!! (Flat spots in different places and the like).
It was suggested that I try the thermostat (Cheers Robf781
). And although not improving economy or flat spot and smoke, it has definitley made my temp gauge much more responsive *and removed the smell of being so rich from the exhaust, so I guess that it was rather tired. The next thing I plan is a change on the MAF as they can tend to go without necessarily bringing up a fault on the ecu (am I right?), but when it was last in for a service I was told that both MAF and lambada were dandy.
Sorry, I feel like I'm droning on a little but I'm more in a position to get it fixed now after having undeniably having the stupidity to spend £750 on a service, cambelt and variator change at an Alfa place that unbeknown to me was to close two weeks after and not be able to put things right. (No I'm not bitter)!
I have read recently that the variator can affect the MPG and perfomance, but my top end seems to be fine (from what I've read, that's what is affected most) its more the bottom end for me (to a certain extent more than normal being the 155BHP '99 model, knowing they are less responsice in this range). And its supposed to be a new one having had it changed.
(BTW I used to get about 30MPG but now vary between 21 and 27. I Don't have a problem with water going down in the cooling sytem either. Its only done mid sixties in mileage too).
I got hooked by Alfa by Dad having a couple of Alfa Sud's (Grandad one too), then I thought it'd be silly for me to get another after a few problems with my old 145 boxer, but you can't keep away from them - problems n all!
So if the the MAF change I plan is wrong, and I guess please, if anyone can make sense of my ramble, at this late hour of need, can anyone tell me if the variator I had fitted could be fitted incorrectly (can you fit a variator incorrectly), or if there's anything esle that you think could be a problem!?
I'd be extremely grateful for any input, output, questions etc.
Hopeless and hopeful,
