Last night I was driving home from New York City and sitting in stop and go traffic for about 30 minutes. Anyways, I felt like the car had a lot of built up pressure on the gas when i was riding the break, so i put it in neutral since i was stopped and wanted to see if I could bring the RPM's down. Now here's the problem, it went up to 4000 RPM without me touching the gas and the car at a complete stop and it continued to go up, so i threw it back into D5. Then when i finally got out of the traffic and was still in D5, I decided to see what was going on, so I just let off the brake and the car accelerated to 30 MPH without me touching the gas. Now I know the obvious comment is that I was in cruise control, but that was the first thing i checked and that wasn't the problem. Basically I'm wondering what would cause the car to a) build up RPMs in neutral and b) get up to 30 MPH without me touching the gas while it's not in cruise control

plus the rpms shouldn't build up in neutral regardless of whether cruise is on, i think.

Thanks

something is definately wrong....take it in for service if it continues.

The trottle body could be gummed up and causing the butterfly to stay partially open.. just curious does the gas petal seem to stick when you first touch it to accellerate? if so the T/B is deff gummed up.

take it in to the dealer

No the accelerator didn't seem to stick at all. This was the first time this has ever happened, If it matters at all I'm at 17,000 miles and have never noticed this before. Also, once i accelerated back to normal highway speed it was fine, so is there anyway that just riding the brake for 5 miles or so could cause the problem.

I had that same situation however it didnt rev that high but mine was a constant up and down rev'ing..i took it to acura and they were saying its because of the fact that I have nitrous installed and it taps into the TPS sensor...basically the tech stated it was doing it cause the throttlebody was getting hot.....when it does that...just tap the throttlebody with something and it should stop..i know that sounds weird but thats what they told me to do and it worked...later

i would bring it in. it sounds like the T/B or the idle speed sensor

Yup ! Something is not right. Bring it in to service ASAP. May be a leaking vacuum line somewhere too.

Good Luck !

Sounds like the the throttle cable... prolly nothing more than just a cleaning of the cable or a readjustment. I would still take it into the dealer and let them take care of it, just in case somethign else comes out of it in the future... it was documented.
