2004 1.8t quattro 6speed

During the weekend i changed my engine oil and spark plugs (Denso Irdium) i have notice during today while i was driving that when i push it right over 3k rpm that my car jerks and my rpm become rough. But this only occurs only if i push it and goes over 3k rpm.. any clues?

Also i need to recharge my AC i notice there are 2 pipes one small and one big on top that goes into the passenger side... and the little pipe has a black cover over it... is that where i would recharge it at?

 

Check the fault codes, more than likely it will have a miss-fire on one of the cylinders. Then take out the spark plug again and make sure there is nothing wrong with it, if its ok, then its the coil for that cylinder.

 

Maybe you didnt gap them the right way.

 

how do i gap them??? i bought them from ecstuning and i thought it would of just been a plug and play.... also i never used any anti seize compound or anything on them, they are just put in raw... is that wrong?

 

It depends on a spark plug and setup u got. If u are pretty much stock, id say go with 0.28 -thats the most common gap.

 

Man, i was trying to type and put some pics but it doesn go thru. Second pic from top is the Gapper

hmmm the pre gap is 0.4mm on the spark.. but i will try to pre gap it lucky i saved one of the old ones... thanks

about the AC is it the two pipe going on the top going into the passenger side?

 

Usually, the gap on old spark plugs is way more than 0.28, so it wouldnt really help measuring it, but who knows.
This might help you
