Engine revs like mad anytime you aggressively accelerate while driving. Then it continues to rise without pressure on the accelerator. It's like driving on cruise control that gets faster. If clutch is depressed the revving raises to the point that it sounds as it will blow up. If I shut it off, it revs at startup and smoothes out to perform normally until aggressively accelerated again. If you ease along, slowly pushing the gas. Every second monitoring it while shifting, backing off every so often.I can drive 20 minutes pushing to 45 (when I'm really good, it's so very touchy) or so before it will ultimately do it. Have also found if I come to a stop (hard to do since it revs so high, I'm eating my brakes) and go into reverse, back to 1st, reverse, 1st, reverse, 1st.5 or six times it evens out and resets itself. It's not showing any codes. Has had full tune up, checked for vacuum leaks (none), new 02 sensor. Also, I can minimize its revving by running it extremely low in the gears (ie, in 4th at 30 mph, 5th at 40, my tachometer hasn't accurately worked for years, it either lays flat, flutters or spikes). It mostly occurs when in 4th or 5th. Interesting side note, if I shut it off and restart it. The gas gauge reads as empty for a couple of miles (even when full) and then goes to its correct position and functions normally. And, when it first started happening, I was able to shut it off and restart it in rapid succession, now.I have to wait a 30 secs to a minute or it won't turn over. Making its timing in traffic difficult to say the least. And, reversing at a stop light and going forward and reversing is unsettling to the drivers behind me, ha! It's got to be something with fuel intake and its regulation, yes? I'm definitely burning extra gas and getting terrible mileage. What part, what sensor is the culprit? Thank you for any help you can offer! Have a great day!
have the same problem?
