1995 SL2 - Intermittent idle/stall issue

Bill 11 March 2005 01:58:37
 I have a 1995 SL2 with 102,000 miles that is not regularly used. After
it sits for a few days, it won't idle correctly. On cold start, the
idle settles at 700-750, but as soon as I use the throttle and then
back off, it will chuff along at 400-500 or, more usually, die. The
problem persists after the engine gets to operating temperature - when
I release the throttle, the RPMs plummet to 400 or death.

However, if I nurse the car through a half-hour or so of this, turn it
off and let it cool completely, then restart within 12-24 hours, it
idles pretty normally - cold at around 1300, warm at 850, and on
throttle release gradually declining to normal idle. It continues this
during periods of regular use, but if I let it sit for a few days the
problem returns.

I've recently replaced the thermostat, valve cover gasket, plugs and
wires. There are no lights or codes in evidence.

What should I try next?

 Thoroughly clean the throttle body and air intake system. Make sure you get
all the deposits from the throttle plate so it seats properly. Also throw a
can of some good fuel injector cleaner into the gas tank and burn through a
full tank, then re-fuel with new gas.

 Glad to see your problem is fixed, but What exactly was the problem and what
was done that fixed it? For the benefit of others could you include the
original description in the future?

There is no history attached and my news service deletes threads after two
weeks so it appears the problem description is long gone. (Others likely
have the same archiving policies...)
