Electrical connector at distributor -- they break and short out. No
promise, but it would cause that sort of trouble. Bad connection at
ECU. *Maybe* throttle switch -- should close at idle and full
throttle. Bad connection at ignition module or coil. If 1.9l, bad idle
stabilizer box or connections thereto. Prolly lots of other things. Get a
digitool from Darrel Boehler to help sort out possibilities -- it shows
coil pulses, FI pulses, fuel pump power, throttle switch; AFM, O2, T-II,
T-I sensor outputs.

Obviously you've never looked at a mid-'80s carburetted engine. Those
folks must have owned stock in spaghetti factories! Seriously, it's not as
bad as it looks, even makes sense once you've seen a diagram.

Propane, WD40, starting ether if cautiously waved around suspected areas
will cause a change in the idle when they get sucked into a leak. Propane
obviously the neatest. I'd vote for it or WD40 as safer. The ether scares
me. Both the liquids put a lot more actual fuel content around the engine,
but the WD40 has much higher flash point.

So where in RI already (I'm in Providence)? And is it true that our fair
State of Rhode Island and Providence Plantations would fit into the King Ranch?
