About a month ago, I cleaned the carbon build up in the intake manifold. An odd thing that occurred during the intake manifold cleaning was that the PCV valve failed, the PCV itself has nothing to do with the inlet manifold cleaning itself besides it needed to be taken off. How it ended up to be broken just that day is an amazing coincedence or a mistery. I drove the car for 4-5 days with a cleaned intake manifold and the broken PCV, until the new PCV was fitted. The car felt great, like it was much more responsive, it seemed to pull off much better (or at least the same). And then surprise, after fitting the new PCV, instant change. The first half a mile I was driving off the dealers, everything as mentioned in the title. The car seemed sluggish in pulling off in lower gears. A strange sensation, like the car has 180 bhp..
The car has 59k miles, it's 99% stock, everything done regularly at the dealers, oil, sparkplugs, haldex oil, cam follwer etc.. etc..
I noticed the change when the new PCV was fitted, but I was told that a PCV should not have any influence on the car's performance, prove me wrong. (I had a 2. revison, and now the last 5th or 6th revision)
I have a K&N air filter, and I read that the oil from it could block the MAF sensor in time. But like I said earlier the change in performance was instant, and the K&N's oil could influence the car's performance in time but not instantly.
I don't know what else could have happen in the time when they were changing the PCV (10 mins) that could have influenced the car's performance? They needed to take off the engine cover, they unplugged the MAF sensor. Could it be something with the MAF sensor plug? Or is it just the new revisioned PCV?
I will try to put the old one back tomorrow and see.. and have them to measure some fuel/air ratios with VAG, if it is possible?
To try and point to the problem.
P.S. recently I had a big problem, I could not overtake a 2008. BMW 530d(197bhp version) in the straight, aldo I wasn't in ultra high revs, and I did pass him and leave him in a car's length (in my lane), he was on my rear bumper, and because a curve was coming, and I needed to get in front of him in his lane and go into the curve, I was doing 118 mph at the time, and decided that it would be too risky to do such a thing, I stepped on the brakes, and he just passed next to me in his lane
Maybe it's just my imagination, maybe I underestimated the fat 530d, maybe It was a short straight, I don't drive a Formula, but still, a good 70bhp stronger car should have overtake it without a problem.
What could have caused my car to become sluggish in a day? What to look out for?
HELP ME
