This may be as simple as a bad idle air control valve which controls the idle , it may also be a weak fuelpump, i would first have the fuel pressure tested to make sure its good, then i would clean the throtlebody with cleaner and replace the idle air valve. the engine it must not be skipping due to a sparkplug or sparkplug wire, there are many things that will cause this. you will neeed to do some checking and make sure the engine is operating good, is you have a bad idle air control valve you should be able to hold the gas pedal a little and keep the engine running after a few minutes the engine should run okay with you holding the pedal , keep in mind this is a 1987 tempo i dont know how many miles are it or if the engine is in need of work but if this is whats happening then try cleaning the throtle and replacing the iac valve. good day.
maybe it didnt run out of gas but just shut down, if it did run out it may have sucked up dirt from the botoom of the tank causing the fuelpump to lock up, what you can try to see if the pump starts again is to spray starting fluid into throtle body and cranking the engine, the engine should start and will die out after fluid is burnt but may stay running if power stays to pump and it frees up, you may have to try this a few times, if you spray and it doesnt start then you may have a diffrent problem. make sure to have someone hold pedal to floor and spray for 3sec, then release gas pedal connect hose to throtlebody and try to start. good day.
Most cars have the throlte postion sensor on the side of the throtlebody, this car has two tps sensors and uses a motor instead of cable to control the gas (throtlebody). you have one sensor on the gas pedal under the dash and two more inside the throtlebody, to replace these you must replace the complete unit. make sure to diagnose the problem before just replacing parts as this is costly, good day. heres a diagram to show you where it is on a 2.0 engine on saturn but yours is 2.2.and is the whole throtlebody.
luckily deisel in a gas engine will not wreck a motor but you have to take the tank off and drain it completely. when full of gas again may burp a bit but in no time purrs like a kitten....luck that wasnt a diesel with getting gas put in it that will wreck a diesel if you start an run it if no start same u can drain it off.flush tank ....but with a gas engine a little diesel will probably black smoke a little but should clean more than harm...thanks for using fixya.
TO clean the throtle plate use a small tooth brush and some throtle body cleaner. remove the intake hose, spray the throtlebody and then open the throtle plate and spray plate , use brush to clean body and plate then spray clean try not to spray to much into engine , after its clean then start the engine you may have to hold gas pedal down to start as it going to be a little load up with fuel from the cleaner, some time sit will start up on its on and run a little rough for a few seconds and clear up. As far as the mass sensor this needs to be cleaned with mass air flow cleaner, this is a spray like the throtle spray but is made for that sensor and drys fast, spray the two sensors inside but dont touch them or move them spray as close to them as you can to clean them, good luck.
You may have a dirty throtlebody or a bad idle air control valve, start by cleaning throtlebody with an old tooth brush and some cleaner for the throtlebody then if it still stalls replace the idle air control valve. you can also have the computer scanned for codes the computer will store a code when the engine doesnt run wwithin specs, for example there may be a code for the idle air valve. you can go to any auto part store and they will scan the computer at no charge.
This may be due to a dirty throtlebody or bad idle air control valve, using crab cleaner clean the butter fly plate or also called the throtle body plate, spray area and clean with a toothbrush and this cleans it good, make sure to open the plate and clean both sides and housing, when restarting you may need to hold gas pedal down to get it going and clear it out, with thew engine running spray cleaner into the idle valve hole, rais eidle a little and spray a few times, the last thing is if the low idle is due to a misfire like its skipping then you may have a bad wire, (sparkplug wire) but clean throtlebody also, hope this is helpful to you and good luck.
