Just got some new fuel injectors. Skp fuel injectors from rockauto. The car has been struggling to start only when it’s warm. Starts up just fine for cold starts. Tested them and they seem to be reading the correct ohms. Not sure what to do.

Did the starting issue occur before or after replacing the fuel injectors?

Why were the fuel injectors replaced initially?
 
#6 ·
At what approximate mileage were the injectors replaced? Were the old injectors tested? Were they discarded?

All things being equal, it could very well be the fuel injectors that were installed.

if you can get a tech 2 and fuel gauge you can do an injector balance test 3 times on all injectors and read press drop, if that passes leave gauge on rail and see if press drops with car off, would indicate a leaking inj or fuel pump ck valve

If possible, could remove and return the SKP fuel injectors. Purchase and install the AcDeclo GM genuine fuel injectors. A variety of things can cause an engine to sputter and at 138,780 miles would not have replaced the original fuel injectors based upon an undiagnosed stutter

That's a possibility.

If you are replacing injectors for maintenance, ALWAYS get OEM. I would recommend you send your stock injectors out for cleaning and flow testing and return the injectors you bought.
