car acting up when Im driving kinda sputters and hesitates when i drive just happend tonight what could be the problem is the opti cause i changed the plugs and wires?

 

Need more information. At this point there are so many things that could cause the problem it would be better if you started with information regarding what if anything has been done during the mileage you didn't state. For example. Tune up's. Even an opti spark distributor will require a cap and rotor as they wear at least as fast as any other cap and rotor. You mentioned plugs and wires. A must have during a tune up as well. But so is an ignition coil and O2s. Air filter and fuel filter is part of a tune-up also.

What if anything has been done to clean the injectors? IAC ever been cleaned, much less the throttle body?

Oh and let's not forget, is it setting any DTC's?

Your turn.

 

it has about 139xxx miles I just changed the plugs and wires but I noticed the problem only occurs when im driving at night when its really cold out.

 

Its not throwing any codes neither no check engine light but lastnight when my phone charger was pluged up in the car it wouldnt start and the security light was on so idk if thats causing the problem???......

 

Did the problem start BEFORE or AFTER you changed the plugs an wires?
