Missfiring The car started to missfire badly after i changed the spark plugs, I went throught the wires again and plugs. Now am worried and i dont know whats going wrong with the car. I changed the plugs because the car gets lazy after it shifts to 2nd nd 3rd (A4) and i thought it might be from the plugs because they were too old and now the car missfires after the plugs replacment. Any idea what would be causing the missfiring?

I've done my plug and wires a few times so I can put in my 0.02 cents in. First of all what kind of plugs did you use and what did you gap them? What about the wires, did you replace those as well? Mine did the same thing but it was mainly the 02 sensors that was causing the backfire. But even after that it still was doing it until I changed my wires and replaced a couple plugs which was gapped a little bigger then the rest. Hope this helps bro since no one else replied back to your thread.

Yes, if you haven't gotten a tune after your longtube install then you will need a tune bro. That should solve the problem with running really rich like I was and I was burning way too much fuel as well.

I think its because of the tune . The car ran weired the second day after installing the LT and it ran and sounded very lazy untill i give it half throttel. The tuner is 400km far away from my town, is it okay to drive it till there with out causing any problem?
