when was the last time you changed your air filter? it could just be choking

 

Hello,

After my car went to the dealership i started with these problems, I loaded the C&L CAI and Loaded Tune but the car was dead with RPMS from 0 to 500 until is dead.

I put back my stock filter and stock tune and im having this problems with RPMs at 550-600RPMs.

Sometimes when changing from IDLE to 1st Gear and start running the car vibrates as if i did a bad clutch disengage but i didnt im sure of that.


Thanks

 

does it seem to accelerate any slower? any problems besides idleing and shifting from 1st to 2nd?

 

I dont feel the car slower, but sometimes when im in 1st gear and try to accelerate the car vibrates as if i did a bad clutch-pedal off, I mean when you start pressing the pedal to accelerate and taking off from clutch, if you are doing wrong it vibrates as if the car is going to dead but is not, so i just press the clutch again accelerate more than usual and then take off.

 

hmmm, so ur saying it feels like its going to stall inbetween the shifts?

 

yes but just in 1st gear. No problems from 2nd to 3rd and so on....

 

I bought an 05 in Dec. and had all the same issues plus the checkengine light was on. Cleaned the TB and mas air and it fixed everything. Just make sure you clean the TB very good, took mine off the car and cleaned it. Hope this helps you out.

 

the 4.6L 3-valve has an extremely overproductive PCV system. You wouldn't believe the amount of oil I pick up in my catch can. It's probably pretty gunked up in there.

 

Hey Thanks for the replies...


I already bought my 2 cans, one to clean my TB and the other one to clean my MAF Sensor.

To clean the TB i need to remove it ? Does anybody have instructions on this ?

For the MAF Sensor i just need to spray it on the sensor ?


Thanks

 

As long as you can spray around the butterfly valve, I wouldn't remove it.

Spray the inside of the MAF sensor- carefully. Let the cleaner work- it will remove the grime and than flash off (evaporate).

The vibration issue makes me think that there's a misfire. Does the vibration smooth out?
