Starter My element has a hard time starting after sitting for 24 or more hours. It usually needs a jump to get going. It runs rough for a bit then after a few miles it's ok. Sometimes it stalls several times. Is this a starter problem? I've replaced the battery and the alternator is testing fine.

SOURCE: rough idle stalls at low rpm's

hello first check your idle with the car running foot on brake see were your rpm reading is if your below 500rpm check your label underhood for your curb idle setting second see if theres a adjustment screw you can increase were your gas cable lever rest against your set screw underhood if you feel confident enough remove your iac motor idle air control valve if the bore were the end of the pintle extracts out to close has varnish builup our carbon it will stick creating vacuum leak type senario causing stalling rough idle sometimes even no start conditions good luck

Did you set the ignition timing after you installed the dist.? If yes, I'd say you got a bad distributor(the one you just put in) since all the codes you're getting are directly for sensors located within the distributor.

Could be a fuel pump that is going bad. Some times when fuel pumps go bad they cavitate and pump not just gas but also air. If you get too much air in the line and not enough gas the car won't start. Have a mechanic check your fuel line pressure.

Hi
Replace the copper contacts inside the starter motor, it connects the current to the rotor once the bendix drive gear is engaged with the ring gear.

Probably when the dealer is testing it is fine because the problem is intermittent. There may be a dead spot in the starter so when it hits that spot it acts up but other times its not on that spot its fine. Replace your starter and you will probably get rid of the problem.
