evening guys.

just swapped my 2.6 vectra for a 156 sportwagon 1.8 (y reg).

Anyway i dont know if its because im used to the 2.6 but trying to accelerate from 50 - 80 in 5th gear took approx 15 seconds. I also was going down hill and it struggled to get to 70 foot to the floor. surely it shouldnt be like this? their is no warning lights on the dash either.

A 1.8 is bound to feel slow compared to a 2.6 Vectra. It is down around 60bhp plus a shed load of torque.


50-80 in 15 seconds in top gear is probably about right. You need to use the gear stick and drop a couple of cogs to get it to move.

It may be worth getting it looked at though as it should do more than 70mph quite easily.

Do you have any history with the car, with regard to belt changes as well?

Apart from being slower the 156 is a much nicer car though. :cool:

Generally speaking the TS engines don't really start to develop their power until 3000 revs, , so as said you're better using the revs rather than trying to slog it......but I'd suspect that you may have a problem with your MAF (air flow meter) if it won't rev properly downhill....it may be worth trying unplugging the MAF and trying the car with it unplugged - it probably won't idle properly but may well drive better........

yep they are a nice well handling car but the 1.8 has no b4llocks from 3rd to 4th

Cheers for the replies guys. Yup ill just assume its me not used to dropping down the gears any more lol the 5th gear in the vectra would pick up from 40mph right to errrrrr the legal limit 70 lol ;P very quickly. I have history from 2001 - 2007 the mileage is 109k with 2 timing belt changes, one at 60k and one at 100k. Your right my cousin had an alfa 156 about 5 years ago and i loved it. ever since ive wanted one and now i have its a much smoother drive and i now feel happier driving it lol. When i did give the car some beans at about 5.5k rpm the engine sounded like a spitfire (weird ) i know never heard that sounds before, could be a problem but sounds good lol

Reading the bhp figures aint that bad. the alfa according to parkers is 140bhp - the vectra was only 167

Not Y195 TJH by any chance?

In any case the 1.8 thrives on revs, more the merrier BUT make sure you check the engine oil level weekly!

Enjoy!

i suggest you get your codes read off your ecu ....remember P0100 P0110 will be logged ....thats regards unplugging maf .......... i think you may have a coil pack problem or a mis timed engine from previous owner who couldnt live with the engine in its state

Have you got the receipt from the last cambelt change?

If so was it done at an Alfa specialist or a regular garage?

Most regular garages won't use the correct tools to time the engine, and if the timing is out it will make the engine loose power.

was done at a regular garage

andrews garage services ltd @ helensburgh.

dont think the car is down on power but as before i wasnt using teh full range of gears, was used to using mostly 5h gear in teh vectra from 30 and above. i dont usually race the cars about either lol quite a relaxed driver lol

It might be worth calling them and asking them if they used the cam locking tools. (If they can remember)

If the belt is done without them the timing will be out, and you will be down on power.

Another sign of it being done without the locks is Tipp-ex on the pulleys. You could undo the top part of the cam cover and have a look, it is only a few screws.
