1987 924s Stalling

Hey gang.
well,i have been reading post of this problem for about 4 hours now, so I will post my own in hopes of an answer.

1987 924s 116,000 miles. Daily driver for the last 20,000 miles 130 miles each day.

Problem: after 10 minutes or 60 minutes it will die. loss of power/rpm. i can keep it going for a while as long as I keep the speed up. when I get to a stop it will shut down and not start for 10 to 50 minutes. Then it will happen more consistently.
in the last 2 months of sporadic driving, i have replaced the following;
fuel filter
fuel pump
fuel pressure reg.
dme relay.

???? dme/ecu and are they the same thing/ anyone got a spare to test with?

HELP.

I am at the point of asking myself, do I keep chasing this issue or get a 928.

Thanks for all input

John

I always hate to tell people this.... but get rid of your 924.... I have had later and earlier year ones, in beat conditions and some in good condition with rebuilt motors and trannys and they ALL have been trouble. They are money pits, do yourself a favor, if you want just a reliable long term car, get a 944 NA. The last 924 I had, I ended up putting over 5 grand into the car thinking it would solve all my problems.... was I wrong. All the money spent could have gotten me two immaculate 944's, but I was blind and could not let go.

firemn131, John,
Welcome to the board,

Your car starts and runs but...stalls and shudders.

Vacuum leak. Start with the easy stuff to fix and go on the hard parts.
Clean your grounds.
Use the troubleshooting link from www.Clarks-Garage.com:
http://www.clarks-garage.com/shop-manual/ts-01.htm

Go to the section on "hesitates and stumbles"

Vacumm leaks are a big problem and most hoses that are bad are under the intake manifold. The ICV hose cracks by the ICV. Reoplace all pinch hose clamps with quality fuel injection or German screw type. Look under the "J" intake boot. These nipples crack. All vac lines and connectors.

Here is another trouble shooting chart:


OR


Do the simple stuff and let us know if it helps or we can then advise more.

Stefan,

I initially was surprised at your response and then looked at a few of your past posts and saw you were referring to the "EARLY" 924 and not the 1986 ROW and 1987 & 1988 924S.

I can see that you put a lot of time in your 1982 924.

I can agree with your feelings for the upkeep on the early 924-I owned two.

You cannot put the 924S in the same mechanical category with the Early 924. Yes the body and interior is similar, but looking at the PET of the 924S and the early944 it is much the same.

Was this a joke or humerous poke at 924S owners in the USA from a Toronto, Ontario 944 owner?

No sir nether a joke or a poke , I have had a later 924 as well, maybe I am just so crude towards 924's since I have put a large sum of money into all of mine and everyone of them has always treated me exactly the same... I just feel it is a warning and help people not make the same mistakes I have.

I suspect you need to adjust the crank sensors or sensors are loose... when it gets hot then stalls as they expand from the heat the sensor gets too far away from the crank to start... once they cool it will start right up

Did you ever figure this out, one of our 944 track cars has been doing this, replaced the Speed Reference sensor harness with a Lindey Haress, but now, it will be idelling fine, then stall, and won't start until it has sat for a while
