Car starts and shuts off a few times and engine lite stays on.car runs good.new dist.and cap and rotor and plugs.codes said dist. sensor and o2sensor.

Probably you have a lean fuel mixture for cold start up and running, but performs normal when the engine has reached operating temperature. So check all items responsible for fuel mixture such as fuel pressure and flow, air leaks ( use a smoke machine for this) choke system ( if carburetted) , engine coolant temp sensor.

lots of things can cause a misfire,most times its electrical check spark plugs,wires
dist cap,rotor.always stay with ac delco brand.is ck engine lite on??

just a thought, remove valve covers and check lifter action, also check compression

1/ Have you fitted the spark plug leads in the proper firing order.
2/ Look inside the top of distributor Top (this is not the first time a new distributer cap has very small crack) or the rotor arm is fitting the cap properly. Hope this helps Best Wishes, Malcolm Campbell.

sugar in the gas

ohm test plug wires, check cap and rotor. anything out of spec replace

You should begin by static timing it. Mark #1 location at distributor on engine or something you can refer to later. Remove Dist. cap make sure the distributor rotor is rotating when engine cranks, If it does not the timing chain broke. If it rotates:
1. pull #1 plug, place thumb over plug hole and rotate balancer with socket wrench till it blows your finger off hole. This is #1 TDC compression stroke.
2. look at distributor rotor--it should be pointing at #1 location mark you made earlier if it is you have a spark issue.
3. If it is not pointing to #1 you remove Dist. hold down bolt under Dist. and carefully pull the dist. up while rotating rotor.
4. You will need to advance the dist. a few teeth past#1 (rotating Rotor) then re-install dist. if it doesn't line up to #1 keep repeating step 4 till it does. After you get it right you should be good to go. A timing gun will be needed after to clock in the timing after installing the distributor.
Good luck!!!

Check the choke in the carb, might stay stuck in the open position when engine cools down. After the engine is cold, check and see if the choke is closed, if not close it by hand, and see if that works.

if the check engine light starts flashing its probably setting a code may have an injector problem

i think the dist is adjable try advanceing it some times the after market caps are a little diffront
