HELP!

My base model '93 Stealth (~120K miles) has run rough at low RPMs, eve
stalling out at stops for quite some time. Doesn't happen when cold, a
RPMs are higher. I did new plugs a few weeks ago and changed the oil an
air filter. After that work, things seemed no better, but no worse.

Now, two weeks later, the car is stalling out even when driving. Spar
plug wires "look" good. Could it be clogged injectors or fuel filter?
think I can get to the fuel filter and change it. What about th
injectors? Does any of the fuel tank additive stuff actually work

Thanks

G'day Joel,

I think your car is terminal. Your best option is to park it in a quiet street and walk away
from it. Other Mitsubishi owners will appreciate the parts in it that
still work.

I had a '93 ES 5-speed and really enjoyed it.

My guess is a vacuum leak, maybe more than one. Remove and plug each
vacuum hose to see which one, if any, are leaking. If the brake booster
diaphragm goes that would easily kill the engine at idle.

Another possibility is the PCV valve. I have seen new defective brand x
parts fail that caused rough idle. Same routine, plug it to see if the
rough idle goes away.
