Look really closely when it's running, and see if it's pissing fuel around
the body of the injector - you might have missed a seal/washer that goes
around the injector body, and now it's pouring in the gas.

Do it soon too, or you'll overload and fry your cat.

He better not say "miss at low RPM". :)

That's what I'm thinking, if it was running like a clock before why'd he
replace the injector? Probably just misdiagnosed the original problem.

I replaced the injector , because it was leaking .

Come to find out NAPA sold me a bad injector.

The Stumbling problem is still there. On exceleration.

When pressing the gas , the truck stumbles .

Still no resolution for this problem.

I did have it diagnoissed , nothing came up .
