allright lol i have a question when i drive down the road and push the gas all the way down it feels like the car jus doesent want to get up in go but it doesent do it all the time so i dont kno whats wrong i let two of my friends go with me and one felt it and one didnt alot and he said it might jus be the spark plugs and wires so if anyone has any output on this help would be greatly appreciated and i did take it to a gm store and they said nothing was wrong but i kno there is?

 

blown cat

 

how would a blown cat do it?

 

by blown i mean clogged

its a very well know problem with our cars

 

ah ok clogged makes alot more sense lol i was thinking blown as in he blew out the insides

 

nope, but if you go to the dealer they will call it blown

 

Yea man well those dummys there said there was nothing wrong with it at all and it does sound a little wierd around the cat

 

meow.

 

yeah if its clogged youll start getting a wierd sound, but if you have a high flow in there im not sure why it would be clogged. Whose high flow is it

 

more info would be helfpul. does it do it totally random? only when shifting? only in low or high rpm's? only wot, or just wih a little acceleration?

 

I would not start looking at the cat until I checked the MAF, injectors, reset the ECU, cleaned out your AEM etc. I have an AEM and until I had the K&N sheild put on, it would bog a lot cause it was damp all the time. if it got really soaked it would actually really stutter and buck etc.

My bet is a dirty maf, old plugs, and a damp filter. Its not your cat.

 

Could be a clogged fuel filter as well, how many Kms on the car?

 

happens at low rpms and when acceleraing its not a big knockin feelin and it only happens randomly it doesent do it all the time

 

maybe you're in too high of a gear and the car is out of it's efficiency range?

 

Sell it...

 

i cant see it being that im guessin the spark plugs because the car only does it ever so often and its wierd u kno i think it might be jus miss firing so im gonna change them first but it jus ticks me off that the dealership didnt find anything wrong with it at all

 

definitely try the coppers first though before you pay another $30 for the iridiums

 

so how much they gonna cost at autozone

 

1.79 a plug i think for the coppers
