RPM jumped up as I was Driving

So last week, I was driving home at night normally. I wasn't heavy on the throttle at all, and just as I hit boost at 3k the RPM climbed up rapidly until I let off at almost 5k. The weird thing is the car didn't move any faster when it did that...

Only thing I can think of is a slipping clutch or traction was broken? I don't know why my clutch would be slipping, it feels fine and has low mileage on it.

I also didn't really feel like the car broke any traction when it did that, everything was still straight on or maybe I couldn't tell. One clue is I did happen to drive over a water spot because the sprinkler systems here are retarded

What do you think it could be?

Could also be the tach itself. Mine is like that. Jumps around on occasion.

Sounds like the clutch. You may want to remove the viewing panels on the tranny, your rear main seal could be leaking.

The actual engine's RPM does go up so the tach is fine

How would the rear main seal leak? This is like the first time it's happened, it happened once before but I felt the car actually swing out. Sucks if the clutch is bad already

Sounds like a slipping clutch to me.

To be certain, drive the car in 5th gear at like 30mph and just try to accelerate. If the RPMS jump but the car isnt going anywhere, the clutch is slipping.

What he said, it could be the gauge, but it sounds like your clutch might be slipping, just take it on the freeway and find out.

AS soon as I added power to my car, the clutch started slipping. Sounds like your problem.

Guys, he said the actual ENGINE RPMS jump, not just the tach so he knows the tach is fine.

My money is still on the clutch.

Especially now that you say you're on the stock clutch.

this is how you know when you went hardcore on your clutch and yes when the clutch is slipping you can
step on it and ACTUAL rpm will go up the car will just move slow no fast acceleration

old (and i wasnt the one who drove the s#it out of this clutch it was the previous owner)
