i've been tracking down a lambda 2 CEL for a couple months.
car runs fine but throws CEL at idle, goes away with increased throttle, sometimes (rarely) dies at idle, runs rich (carbon plugs, 18 mpg city 23 hwy).
sounds like a vacuum leak to me. at first I sprayed carb cleaner around everything I could see without any change in the idle. the boots/hoses all look ok but could definitely still have a leak. dipstick o-ring looks ok.
i've tested the o2 sensor and it seems to be working within normal limits (based on multimeter test)
c191 replaced. thermostat replaced.
fuel/air/oil filters all replaced. ignition system (rotor/cap/wires/plugs) replaced. ICV is working.
So now I just want to fix it.. 95% sure it's a vacuum leak.
is it worthwhile to pay someone to do a smoke test ($80) to pinpoint the leak or am I better off just putting that money towards buying new boot/hoses and just replace everything?
