When I'm just driving around and go to shift gears, the rpms rise for a second or so before dropping. This is with my foot completely off the throttle and clutch down. It happens a lot of the times althought not 100% of the time. Whats going on?

 

i had a similar problem but my rpms stayed up. it was gude tas or tps wasnt setup for my car. once i put on my stock one car ran great again. so it might have something to do with that.

 

bump

 

just to make sure, no CEL's right?

 

correct, no cel's

 

How much does it go up? When are you letting off the throttle? Vacuum leaks?

 

~500rpms if it goes up, sometimes it just stays where I shift and just floats there for a second. I've checked all teh vacume lines and they all look fine

 

Try cleaning your throttlebody and your IAC valve with a can of throttlebody cleaner. Maybe something is sticking or maybe some dirt are stuck on the sensors.

 

I had the same problem.. it was very annoying... damned if I could remember what it was now, though I think it was just running rich + the excess fuel on the plugs was burning off between each shift, keeping the RPMs up... but I really can't remember I changed SOMEthing and it went away... augh. If I can remember I'll post it. Sorry

 

arent u the guy with the pop pop pop at high rpms?
your running hondata, perhaps its in the tune?

 

see the popping doesn't happen at high rpm's, it happeneds after I top out a gear and switch gears.

It might be your fast idel valve.

 

mine used to hold there for a sec or two when i shifted, never figured out what it was tho

 

Looks like its running kinda lean
