Sacho Posted May 15, 2010 Share Posted May 15, 2010 So i have 07 2.5gt wagon 5EAT. The car has since i got it with about 32k on it occasionally from a stop with light acceleration shifts from 1st to second very harshly and is like a jolt. that happens from time to time. i would say in an average week of driving maybe once or twice. The new issue is i was driving up on some back roads and was going up a hill and i believe i was in 3rd and the car was about to shift to 4th and it started to surge like 4 or 5 times then shifted into 4th. this had happened probably like 4 months ago going up another steep hill and i thought nothing of it really. Now driving to work today i started getting that surging sensation on the freeway on even ground. surging between 3k and 3.5k. Any clues as to what the heck is going on?! no engine mods besides drop in k&n Link to comment Share on other sites More sharing options...
fredraud Posted May 15, 2010 Share Posted May 15, 2010 Is this engine mass air?? Ive had simmilar issues with the oil from the K&N filter contaminating the mass air sensor wire, and even fubaring the sensor on a few cars. has your milage decreased?
