when i put my foot in the gas when i first got the tc it went alot better than it does now its like its not wanting to it bogs a little at first then it takes forever to rev it never used to do that before i need help on how to fix it, my cel is not on.

 

Clean your air filter?

 

 

Normally a bogging down issue is caused by an improper a/f ratio. Have you done any mods to your car, or bottomed out? If the mass air flow sensor, o2, or your exhaust has been damaged that would cause a bogging issue.

 

I used to have the same issue with my car toward the end of the oil change period...say about 4K miles. I do not know too much technical but I changed my oil from regular Penzoi 10W30 to Mobile 1 10W30 and the problem went away. I do not know if it's coincidentally but Mobile 1 every 5K mile seem to work every good for me. I do a lot of highway and I have rakced up 85k mile on my tC without any more of this problem.

 

how would i know if it is damaged the dealership doesnt seem to think anything is wrong when there definitaly is
