Past day or two I noticed,well I think i noticed, that when i mash the throttle, it seems to hesitate before the power kicks in. Theres no lack of power, just seems to sputter a fraction of a second before she responds. I have a half tank of 93 octane from shell (had full tank last week), popcharger and motodyne 5/16th spacer with 50,000 miles on a 2005 6MT Touring. I have yet to check the cleanliness of the air intake but I cleaned it about 3 months ago and dont really drive all that much. Any ideas?

 

Uprev or any tune done? There is a thread running already for this exact issue.

 

Havent seen the thread for this, no tune or uprev, just spacer and popcharger mods.

 

Im having the same issue, i have intake, headers, plenum spacer, and full exhaust. Im actually getting lag when i hit the gas, ive tried using fuel injector cleaners that you buy at the gas station but that didnt do anything

 

Im gonna check my air intake later, reset the ECU manually. If that doesnt work Ill look into new spark plugs. We'll see.

 

Let me know how it goes

 

Did you try cleaning your Mass airflow sensor? Try the cheap, easy to do stuff first.

 

Yeah...Ive been googling that, is it hard to clean?

 

I had the same problem about a month or so then it progressively got worse. It turned out to be a bad plug. The thing that confused me was that it wasn't a consistent problem, it would be fine at times and not others. I took it in to the dealer several times. Long story short the regional service manager had to get involved and scout my car with a stethoscope over a faulty plug.

 

Thanks, im having that gut feeling its a plug issue too.

 

ehhhhh....just got back from driving it. My guess is the clutch. Ill nail it, RPMS climb but I got nothing for like a half second then it kicks in. Clutch you think?

 

thats starting to sound like slipping

 

Forgive my ignorance...is it the entire clutch ($300 to $500) or just the plate ($150), my google is inconclusive in that aspect.

 

could just be the plate, more than likely just the plate from the description you gave. Do you notice any weird noises when pushing in the clutch or when it disengages or engages?

 

Thanks for the response. No weird noises at all. Tranny feels fine going into all gears, clutch pedal feel is fine, just when i hit the throttle quickly, the rpms climb but there is initially no response from the car for a half second, then it feels like it "catches" and lurches foward.

 

have any with the issue replaced tail lights with aftermarket ones? that's were my issue came in...i bought leds and they were messing with the ecu in my car causing a loss in throttle response...beats me but maybe it will help some of you

 

No, no light issue, my clutch is toast, getting a new one this weekend. Figured should go ahead and get a lightweight flywheel while Im at it. Darn.

 

so it is fixed?

 

still in the shop, getting an aftermarket clutch and flywheel. Hopefully by Wednesday.

 

let us know if it is solved...hate to hear you did all of that and it's still there.
