I just recently installed a new Motordyne plenum (mrev2) and a iso spacer, along with an injen intake. It is definitely to combo to get, btw. Its been fine for about 2 weeks now, but just recently its been acting funny.

Acting funny = in normal driving situations, when I step on the gas in a higher gears, it will rev up alittle then go back down, then gradually speed up. Its really not a problem. Everything seems fine. I still hit the same speeds, but it just flutters for a second once I step on it.

Just wondering if anyone else has experienced this problem.

Ex... 30 mph 3rd gear. I step on the gas. Say the car is at 3000 rpm's, it will give you a jerk to 3500 rpm's, then drop back down to 3000, then gradually speed up.

 

is your car 6sp if so sounds like your clutch is slipping.
NO 100% sure but that is what it sounds like.

 

+1 to that. Sounds like it's possibly your clutch slipping...

 

Yes, clutch is very much slipping. Im having it replaced very soon. lol I have the new one in my trunk. You know what, it could be that. Cause its been slipping allllllot recently, but its almost like it would have slipped right when I pressed the pedal. Not seconds after, and then grabbed again.

Anyone Else?
