I have a 1988 240 wagon. So far I had to replace the fuel tank and fuel
sending unit, then coming home the timing belt broke(replace it with seals
and WP), fuel filter. My problem, it stats and idles perfect, sometimes it
acts like someone shut the fuel off, just loses power, this happens cold or
warm. It happens when I am accelerating hard, if I pull my foot back it
seams to improve but not much. BTW tonight I remove the TB and cleaned it.
Also new flametrap. Could it be the fuel relay? If so where and how do I
get to it(nothing is as easy as my 740 wagon). Thanks


ps it has 164,000 on it.

Check the fuel relay first, actually it is as easy as a 740, it's just
different. Pull the panel off above the passenger footwell behind the
glovebox (assuming LHD) and it's clipped to the firewall, usually a white
box. Pop the cover off and inspect the soldering on the back of it.

Do you have a tach? If so look and see if the needle drops like a rock when
the engine stumbles, if it does then look towards the ignition system.

Check the intake air duct (from Air-filter - AirMassMeter to throttle body)
for splits or cracks.

Got this tip on the Brickboard forum when experiencing similar problems,
turned out to be a crack in the air hose just before the air-mass-meter

When accelerating fast, the engings toruques so the crack widens and false
air is sucked in, engines stalls and begins to hop.

Good Luck

I had a similer problem on a '82 240 wagon, none of the parts were bad and I
replaced the fuel pumps and the relay. Finaly figured out that it was a wire
short by the main fuel pump, just wiggle it a bit and the fuel pump goes on
and off. So if all else fails check the wireing from the relays to the
pumps, with the car running wiggle each wire around a bit, expecially where
they go around bends or where they may move a lot. If the car suddenly dies
you have found a short.

and slam bam thank ya mam it ran like a champ! Thanks for everyone's help.
