I have a ZR2 and it is hesitating after the engine warms up for about 2 mins. I did a scan and it showed code p0410 the Air injector so i gone ahead and replaced that and still doing the same thing. I searched another thread and the guy mention that he solved the same problem by replacing a stuck check valve? Here is the link to the original thread:
p0327 and p0410
My dad thinks it is the fuel pump but i dont want to throw anymore money that doent need to be throwing at i just want to solve the problem. Anyone have a clue?
