Car revving without applying gas?...

Nick911sc · 02-20-2012, 08:05 PM

Alright guys,

I had a pretty weird experience tonight on my way home from my gf's house. About half way through the drive i was stopped at a light, car in neutral. I had 1 foot on the break and pushed in the clutch and began going into first gear. As soon as I put the car into first gear(clutch still in, foot on the break) The car reved up to like 4500RPM's. It wasn't a blip.. It was a steady climb. I pulled the shifter out of first into neutral and the RPM's dropped back to normal. When I put it back into first it didn't do it again. And for the rest of the drive home it didn't do it either.

Not really sure what to think, has this happened to anyone else? 2009 6MT VDC on and SyncroRev on as well

Nope. Hi Nick!

Something similar happened to me once. I was sitting at the end of a parking lot waiting to trun onto the street. Same story -- clutch in, foot on the brake -- and I heard something odd. I looked down and I the engine was climbing from 5,000 RPM up to 6,500. It was doing this slowly. I realized that my foot placement on the brake was very sloppy and I was actually pressing on the accelerator with the side of my foot. No excuse, but I was wearing wingtips at the time.

This or synchrorev malfunction. I'd be worried only if it happens again

Thanks guys, I'm pretty sure my foot wasn't hitting the gas pedal. I slid my foot all the way to the left half of the pedal while it was happening because I assumed that's what was happening. Crossing my fingers that it won't happen again.

Hope everyone's been well since I haven't been around too much!

Hey man this happened to me a couple of times. I noticed it happening when its really cold out and when the car hasnt warmed up. Other then that I have no idea on what it could be but I would like to find out why.

BrianMSmith · 02-20-2012, 10:23 PM

could be throttle position sensor. I had one that acted up intermittenly on a former car. Most of the time it was no problem, was always worse when hot outside.

AhadV · 02-20-2012, 10:35 PM

Cold outside, bad spark plugs, bad coils, or electronic defect. Just from my experiences from the rx8

RedNismoZ · 02-20-2012, 10:42 PM

That has happened to me one time, and a cop was next to me lol.

I think you've encountered the haunted Z ghost .... lol!

Compdoc777 · 02-20-2012, 11:44 PM

I think it is with the synchro rev. Mine is annoying that way revs when I don't want it to. People think I want to race when I am downshifting thing revs for no reason other than to waste gas. I had it off for a while and enjoyed the car a little more. The idea is great, but the program needs modification should not rev match when I am slowing or want to use the clutch to help brake.

Never happened to me but in your case this shit's in your car bro...

The whole idea of SRM is to help when downshifting going into a corner, when you are slowing down. It's intended so you don't use the engine to help slow you down. That's what the brakes are for.
