Not yet. If the level is ok and it isn't burned looking or smelling, then that may not be the problem.
Moving on. Is the 'Check Engine" light or "Service Engine Soon" light on? If so, we need to see what the codes are. Look for maybe a Throttle Position Sensor code. If there's an "OPEN" spot in the TPS, the PCM (computer) doesn't know exactly what the throttle position is and therefore doesn't know what to do with the injectors. It could either starve the engine for fuel or inject too much. Remember, this is just another possibility. I keep re-reading your post and my mind keeps going back to the transmission, though. It's pretty 'cut and dry'. If the RPM's go up but the vehicle doesn't speed up, the power is being lost somewhere. Don't rule out the tranny. Let's try this. Re-post and describe, in as much detail as you can, exactly what's happening and when it happens. Be very specific. This could be a fuel injection problem, and ignition problem, or, like I said, a transmission problem. I'll be waiting for your reply. I'm going to do my very best to help ya.
