Fellow Bricksters,
I bought my used 1984 240DL with the B23F engine in January. I have been,
bopping around town and thought the car was a bit sluggish, but then
it is a 113hp engine. Last week, I made a trip into the Texas hill
country and I discovered some interesting things.
One, the car can barely hit the speed limit of seventy miles an hour,
and this was going down hill. The A/C was off.
Two, EVERYONE passed me on the hills.
The car doesn't ping, doesn't over-heat and starts and runs OK. The
engine has some slight jerkiness from 2K to 3K and if you blip the
throttle it doesn't know whether to stall or rev. When I checked the
timing it hops around when the idle changes.
I replaced the vacuum hose to the ignition module, no better. Anything
else come to mind? Pre-fuel pump, packed up catalytic convertor?
TIA,
Randy

Randy,
Check for intake leaks by spraying around intake manifold and injectors with a water filled spray bottle. A leak, when sprayed with water, will cause roughness. Check all the intake plumbing for holes/damage. Fuel pump pressure and flow-clogged fuel or air filter. Output of oxygen sensor between 0 and 1 volt, hovering around .5 volts, when warm. Timing belt off a tooth? Check all plugs and ignition high tension wiring. Throttle switch adjustment and contacts at idle and full throttle. A good visual inspection of all vacuum hoses and wiring for damage. In short, check all the basics first, fuel, air, spark and compression. Just a quick list. Hope it helps. I had an 83-DL and while it was no rocket it was responsive and did well over 70 mph.
