Jerky while decelerating and maintaining low speed.
My newly purchased 2nd hand 156 1.6T-Spark was giving me a jerky ride when decelerating and when trying to maintain say - 30 mph in urban areas.
Was it fuel starvation? Were the sparks missing?
I was told by the sales and service department at the garage where it bought it that it was an Alfa characteristic. This comment was eventually whittled down to only this model. Then I was told to go away and go back if it got really bad.
Two days later --- when I started the engine it just took it upon it'self to rev up and down, whilst the car was stationary in the drive with no foot anywhere near the pedal.
I rushed round to the garage and asked if this was an Alfa charactristic? No - was the answer, it was "hunting" they said at which point they lent me a 147 1.9 jtd with only 3k on the clock, and took mine in for repair.
A week later -- I was called to pick up my 156. They had fitted a new throttle, and I thought all would be well..
When I discovered it still did the jerky bit I tried hard to ignore it. After a week I could ignore it no longer and I was really pi**** off with the car. So I went back to the garage again, and they just brushed me off. Sneered at me. Treated me like a daft old woman (I'm a bloke!)and suggested that if I wanted to change the car I should stay away from the T-Spark engine which was "quirky".
I had already told them that I thought that if the problem was an Alfa characteristic, that no one would buy Alfa's; but my thinking was deemed to be warped because I traded in a Fiat Tipo TD SX, and an Alfa 156 1.6 T-Spark was a totally different type of car to drive!
Feeling frustrated and desperate I set to and looked for the source of the problem myself.
My thinking is this....the accelerator cable had so much slack in it that it was free to jump about, especially as it's anchor point on the air intake tubing had been destroyed. I took out the slack by adjusting that little clip at the end of the sleeve, and re-anchored the cable to the air-intake tubing. This seems to have cured the jerky ride, and, in addition it has cured the problem of having to rev the engine and slip the clutch when pulling away in 1st gear so as to avoid the dead spot, and the associated embarrasment of having an Alfa that didn't go very well.
The garage don't believe me of course, and still think I'm nit-picking.
I'm just waiting for the problem to occur again.
Or have I really fixed it?
I am a very dissapointed first time Alfa owner, but my car goes really well at the moment and I love it to bits. Time will heal the wounds perhaps.
I would be interested to know if anyone else has had a similar problem? Or is it an Alfa characteristic?
