This has been happening for the past few weeks. When I get below 1/4 tank of gas, the car lunges at high RPM's (kind of like it does when you hit the rev limiter).
Last week, after doing a brake job, I took it for a spin (below 1/4 tank of fuel). 2nd and 3rd gear, above 5,000 RPM, the car would lunge and not fully accelerate. I pushed in the clutch, tried to rev the engine and it choked down, almost to a stall. Took it to the gas station, filled it up, and it ran like a champ.
I know it wasn't just a bad tank of gas cause it's been doing this every time my tank gets low.
I've recently changed the fuel filter in an attempt to narrow down the problem. As is typical, the easy replacement didn't fix the problem.
What other ideas might you guys have?
