spark plugs agains

[t wizzle17]

I installed new spark plugs and wires gapped at about .60 and now my cat starts harder is it because I put in AL 605,s and there. Colder causing a harder spark ?

Just hai atm I do have a few parts waiting to go on

And I'm running 93 if that changes anything

Likely not the reason, prehaps you knocked a vacuum line lose or bumped a sensor.

now my cat starts harder

you mean your car? cuz if your starting a cat I really don't want to know your hobbies

 

[DirtDog]

U shoulda stayed stock on the plugs. Id be willing to bet that's why

 

[Fivefingerdeathpunch]

Running 605's over stock plugs will have nothing to do with its hard starting.

So the plugs need to like "break in" ? But once the car starts it runs great actually better. I just went with basic life time warranty wires were there was ac delco premium wires on it previously

No "break in" periods on spark plugs, they will work no matter what if everything is hooked up correctly.

Something else is the problem, vacuum leak, sensor or maybe even the fuel pressure regulator took and dump.

if its started hard it maybe a dead spot in the starter solenoid but not sure tho

 

[t wizzle17]

Stock plugs I had no problem with it started right up. And I ment car not cat.
