Hey everyone, I've owned my car for a few months now and I've tried everything to get rid of this pesky problem. I'm having power loss at 2400 rpm. Sometimes it happens at 1900. It's with partial throttle. WOT seems fine. I've cleaned the MAF, put a paper filter in in place of the K and N, and finally I took it to a shop that works on alotta LS1 and LT1 cars. He said the scanner showed nothing, but he could definitely tell it when he was driving it. He said that the fuel pressure drops at that rpm level but he's not sure why. The fuel filter was very clogged. He said he didn't even know how it was running. Oops. He put a new one in and some injector cleaner but the problem remains. He said he wants me to put another deal of injector cleaner in on the next tank. Does anybody have any suggestions 4 anything else it might be? For him, he said if that doesn't work I should probably get the injectors cleaned. Any suggestions?

Thanks,
Cole

Injectors / plugs would be where I look next.

Sounds like either the fuel pump or injectors are having a hard time.

If he's showing a fuel pressure drop, I'd suspect the pump before the injectors. If pressure is good, but you're seeing an overly lean A/F ratio via the LTFTs and the O2 sensor readings, then I'd lean more towards injectors.

OK thanks. I didn't ask if he checked the fuel pump or anything. We'll see if this injector cleaner clears up the problem. I've got my fingers crossed.

No solution found. The computer shows absolutely no problems. They replaced the throttle position sensor at the shop, but it's still there.
