You need to ohm your injectors. It can be done in about 5 minutes with a digital volt meter at the harness connector on the PS of the engine. A good range is 10.0 - 14.0 ohms. Following the instructions posted below, check them hot and cold and get back to us with the results.

Good luck

Have your o2's been replaced?

And OEM injectors are going to serve you better, unless you need to go higher flow for BIG HP mods.

The OEM injectors should last longer (depending on gas quality) and require less labor long term to replace again.
