Question

olds alero 99 when i start i press the gas, and as soon as i let go it dies, but if i keep it down it dies after the full rev

been a bit since an oil change

Answer 1

maybe start with the make and model......
doesnt sound like its getting enough spark, loading up on fuel

Answer 2

More specifics would help. You could try stepping on the gas pedal to the floor and holding it there until it starts then ease off some on the gas pedal, but don't let it all the way up - see if it will clear out. Sounds like too much fuel.

Answer 3

Sounds like the engine is getting too much fuel and flooding the engine. You might try holding the accelerator to the floor and cranking it, it may get rid of the excess gas and fire up.

good luck.

Answer 4

Are you sure it's black or blue smoke, makes a big difference. Black smoke mean incomplete fuel combustion. Some causes are: running too rich, dirty air filter, ignition timing is off, choke problem, dirty carb, emissions problem.

Answer 5

maximum probably this may be a results of worn valve instruction manual seals. Your engine pumps oil up into the cylinder head in the process operation to lubricate the valves, the rocker palms and the cam shaft that reasons the valve to open and close. to avert that oil from leaking backpedal into the cylinders, each and each valve has a seal around its stem. whilst those seals positioned on slightly from the valves passing by their midsection holes 1000's upon 1000's of situations in the process the engine's operation, a niche outcomes that facilitates extra oil in the cylinder head to seep down into the cylinders the place it rather is burned off in the process combustion. because of the fact the quantity of oil seeping down in the process recurring operation is comparatively negligible in proportion to the frequency of combustions in the cylinders, there is little seen data popping out the tailpipe. in spite of the shown fact that, once you change the engine off, and pass away it off for a protracted era, any last oil that turn into in the cylinder head once you close up down will seep in the process the gaps in the seals, and deliver collectively in the cylinders. Then, once you start up it up, this is going to all burn off in the 1st few seconds of operation, producing a tell-tale cloud of smoke in the back of the automobile. this will not be an particularly intense subject in many situations. changing the seals oftentimes fees $two hundred-3 hundred in case you confirm you do not desire to stay with the nuisance of the cloud on start up-up, yet till it gets plenty worse that it smokes for all time--seeping so without postpone this is burning very loads of oil as ou force, i'm uncertain i could subject with it. There additionally are some oil ingredients on the industry that is effectual in restoring inner seals. those may be modern in maximum vehicle suply shops, like improve, Pepboys, NAPA etc. in reality, those are chemical components that reason some varieties of rubberoid seals that have hardened and gotten smaller with age to swell up slightly and turn right into a sprint extra elastic, with a view to strengthen their potential to seal. despite if one in each of those scientific care would be effectual on your case or not will count on the quantity of hollow that exists and despite if the textile used in the seals is at risk of chemical interplay with the specific seal restorative you opt for. this is something of a crap shoot, yet oftentimes speaking, you will do no harm by ability of attempting, and it rather is a low-fee restoration.
