Question about Buick Regal
Hi, please check you oil level, ( on level ground). when the car is running place an old rag in front of you and take off the oil filler cap (be careful not to get near the fan, fan belt) if no oil comes out of the filler hole possible fault: oil pick-up pipe (in sump partial block), / oil filter in sump ( blocked), oil pump worn, oil relief valve (returning oil back into the sump), spring weak / broken. the (E C U) ENGINE CONTROL UNIT has many sensors that can stop the engine: but try cleaning the (EGR) ENGINE GAS RECIRCLING VALVE, this valve recycles gas back in to the engine, ( must be CLEANED with BRAKE FLUID) this is a VERY DIRTY job, as this gets block with carbon (EXHAUST PARTICULES). the E C U will detect all of these sensors: the (ECT), TOP OF ENGINE engine coolant temperature sensor rough tick over, (HO2), EXHAUST DOWN PIPE, heated oxygen sensor checks mixture of fuel, can adjust air / fuel, it tries to keep car going / may flood engine. (M A F) mass air flow, adjusts fuel / air retio this sensor can so much fuel to the engine it may flood it. flooded engine mean WET spark plugs. i would put it on dianostic machine to check these out before paying for extra sensors. gerry
