Bad Fuel? Clogged Injector? Bad Fuel Pump? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Hello there,

Proud new owner of a 2010 Camaro SS (LS3/TR6060) (stage 3 cam, headers, full exhaust) & new member on Camaro 5. Car made 470 wheel on a dyno jet.

I got an issue where the car starts to stutter/micro-stutter/miss under load. The car revs up normal It makes it’s first micro stutter at a consistent 2800rpm & more throughout the pull. NO CEL. Live data measured a 60psi-55psi on fuel pressure. The car does have a more noticeable “tick” at idle. This tick is not a lifter tick, rod knock, ect. Possibly a spark knock?

Before this instant, I went and got fuel at a local gas station and filled the car up. Within 6 miles after full-up, this issue has accrued. I’ve added multiple fuel stabilizers, seafoam, hoping to have an easy fix but still nothing.

I did also get this car back from a local tuner 3 weeks ago and has been running great with no issues. I strongly believe that this is not a tuning issue and more a fuel delivery problem.

My plan is to just take the injectors off and clean them. But I would also like to siphon the fuel out of the tank if it is bad fuel. Is there any way to siphon the fuel without dropping the tank? I really just need to find a way to trip the fuel pump. There is no relay under the hood to jump the fuel pump.

Any information would be helpful! Thank you.
