the lamp never lies. ever. this lamp glows, only for catastrophic errors,
like a wire just broke off a KEY sensor. errors.
Chevron Techron is best fuel additive, I never use any but cars parked, are a bad problem parked over 1 year, and worse with low fuel.
drive with the DIAGNOSIS jumper inserted,
next time it fails, the CEL will flash a new code, not 12s.
takes careful eye to see the new code, none 12s, happen..
again the CEL did not lie to you. a fact.
rich on this car
is.
fuel pressure too high
ECU stuck in limhome
or 02 stuck at 0v, due to wire cut or exhaust leaks to it. (rear on 8v. this but possible at header gasket missing or cracked)
leaking injector o-ring pair, can be watched running,
many 8v TBI' are hacked, this injector has 2 wires, and both (not one) are pulsed,(un like MPI)
and one wire goes, dead, then the badguy,cuts the wire (ecu is bad is real prob) and he hot wires the dead wire. BOOM , horror.
a hopeless case now as it will run rich for ever and ever,.... seen many, heard many done like this on many forums.... sad really to see it.
ECT stuck at Frigid )300 ohms is good hot, connector pulled. see ECT tables at kickfix. for all values.
thermostat missing , wrong one or put in backwards.
MAP failing (rare) x10 more likely hoses bad or clogged to it, sure, it will food.
and #1 is, what.
IN LIMPHOME, it will burn 2 times the normal rate of fuel, 15mpg possible horrid.
one lady here is like that now, TPS failed and ecu locked in limphome, and her mechanic, fears this tps, fears doing test to find true cause and fears the 2 page PDF calibration. sad , all sad....
