My car these past two days has developed this almost surging feeling. Its not as smooth pulling off in first. Its really hard to keep it smooth. Ive tried to keep it smooth but it just surge/jerks almost. I dont think its the clutch though because its in every gear, no matter what speed or rpms.. It just hasnt felt smooth the past two days, I just get this surging feeling especially if im cruising at any speed and im using my foot to stay at that speed. It still gives a surging feeling. Yet when I put cruise control on its smooth like nothing is wrong. Anyone have any idea what it could be? Maybe the injectors need to be cleaned??

I guess my car being for sale will be on hold lol.

Also no CEL and im positive no vaccum leaks anywhere.

 

If it was injectors id think itd happen with cruise on, same with maf unless they save the setting when its enabled so ecu stops constant calculations. Maybe throttle linkage to your pedal?

 

Have you been adding/removing any mods lately? I knew you had it for sale thought maybe you'd removed something and not reset the ECU maybe...

 

Ill check that out again but I remember looking at it yesterday and its just as responsive as anytime before. Doesnt look loose at all. Could it be the sensor on the throttle body? I thinl that would throw a code though.

I guess ill check the throttle linkage again and hopefully someone else can chime in too.

 

Only thing I removed was the intake but nothing else.. I reset the ecu as I always do. I even let it idle for 10-15 mins and then I drive normal for a while to make sure it picks up on the changes.

 

If u can hear theTBPS tick when u first turn key to on then its ok id think, like you said would probably throw a code, i thought linkage cause there is a complete seperate control for cruise. Is it possible dirty air filter, partly blocked,maf backwards,vacum hose not attached,water in intake or on maf?

 

Try resetting the ecu again if it still happens,

This may be a pain but, if u can put the intake u removed back on and see if it still happens? If that fixes problem, could be a tune error with ecu not picking the diff. Or maybe youll find something u missed, i know ive forgotten the vac hose once luckly i found it before startup tho

 

I checked everything over again and didnt find anything wrong. I reset the ecu. Went driving around the neigborhood and it feels smooth again. Hopefully it doesnt come back lol.

 

She knows your trying to sell her

 

Lol weird how cars pick up on that

Good to hear man, maybe the ecu had re-learned at idle but not driving

 

Good deal!

Sucks that your selling the car though... Id love to come pick one up I want a manual so bad but any I find for sale are SO far away from me. haha

 

I had this same issue and it ended up being the apps sensor..

Thanks, its actually driving great again. I think the ecu just had to get use to the stock intake again

@bakuro im moving to NC in July so if you want it we could wait until then. No but if I dont get my asking price, Im keeping it. Not rushing the sell.
