Greetings to all, because I have the following problem with my jetta vr6
is a 2000 jetta gls vr6 mk4, the problem until 20 minutes behaves very well in cold, runs perfect, however, after 20 minutes, pulls, feels slow, it feels like drowning, and drawing in low and has worsened lately intense jerking at high speeds, hesitating, does not react well. this is done from small jerking up and after much use, it feels like drowning, more jerking, hesitating
At idle, the engine is working normally and even, no hesitation, and listen well.
I changed the following new components:
NOTE: Vagcom, not shown any code, tested three scanners and throws no code.
Fixed a fake that had the crank sensor harness.
not to do, I'm totally desperate,
Cold morning in perfect starts, pulls great, runs perfect, has power.
I disconnected the 2 O2 sensors and the problem persists, disconnect makes no difference.
Please ask for your help to guide me to know what happens to my car, and I've spent enough money on it and does not look good,
Thanks for your feedback.
