Richard,
Funnily enough.....my Fiesta started doing this the day after you
drove it....you didnt by any chance drive the Saab as well did you?
Seriously though...my car was exhibiting exactly the same problems
that you mentioned...this was a re-occurence of a problem I last
had about 30k miles ago...then it was a incorrectly adjusted
turbo wastegate...this time it was " that the ECU had forgotten its
settings after a service and it needs time to learn these
settings"......I left the car with the garage for an afternoon and it
all appears to be OK now.........I'm sorry but I do find the latest
explianation about the ECU forgetting its settings kinda hard to
believe! Comments anyone......................?
Graham.

2012.2 | Pinking control! | UTROP1::BOSMAN_P | | Fri Feb 05 1993 07:23 | 20 |
| How old is this SAAB?
It may, very likely, have something to do with the pre-ignition control
devices SAAB fitted.
On older, read more mileage or short-distance use model, gets rather
prone to pre-ignition. Pulling heavy loads from low revs, like slugging
uphill, is exactly the condition under which this is bound to show up.
The electronics will try to compensate but under these conditions
nothing short from cutting the ignition out alltogether will help!
Solution:
1. Use the highest grade petrol available
2. "Decoke": Short distance model: give it a very good burn out
High mileage one: ask your garage
3. Have them check the base settings and all the "anti-pinking"
controls.
Succes,
Peter

Thanks for the advice, the car is old its a "W" I think but the guy
refuses to use it for short journey's and uses a bicycle where poss.
and it goes from essex to chester and back every week, this problem has
not crept up it has just occurred more like a defect than a decoke type
problem, but this anti-pink device sounds interesting if it has one.

ps. it was serviced by a SAAB dealer about a month ago.

| Have you thought about the possibility of it being one of the spark
plugs breaking down under load - it is a possibility even if it was
only serviced a month ago.

| Could be the fuel filter, if this hasn't been changed regularly. The
99 has that tiny little one on the left wing. However a similar problem during
warmup on my Saab 900 Turbo (135,000 miles) was cured by cleaning the
distributor cap inside and out. High compression blew the sparks out
until the damp goo on the cap dried out with the engine heat.
Good luck.
