Hey, I have a really annoying problem with my 94 Lt1. It loses revs when I just barely give it gas between idle and about 1500 rpm. Once it's higher than that it runs perfectly fine, also idles completely normal, this ONLY happens when I step on the gas just enough to raise the revs slightly. It has been getting worse and has even stalled out on occasion. Since it runs fine in higher rpm and I have 4:10s on an A4 it's easy enough to ignore most times, but I want to fix it as I have to be obnoxious in a parking lot pulling out to keep the revs up and I'm sick of it. It started when I had a header gasket leak and I thought that when I fixed that I would go away, but it has stayed the same. Should I change my O2 sensors, bad MAF, etc? Looking for ideas on want might be causing it. Also, no check engine light on, if that would narrow it down. Thanks to the help.
