Question:
I recently purchased a 2001 VW jetta with 90K miles on it. It's a 2.0 non-turbo with a five speed manual (I traded from an automatic Explorer). I love the car so far but sometimes at speed of about 55 it's like it bumps a little bit, kind of like hesitation or a toned down version of what it feels like to run out of gas the bump bump before it cuts off, also sometimes it idles really fast when it's first started up and then once on the road it calms right down, this is my first german car so I am VERY gun shy if you are a VW person with experience on these matters or any good advice for a first time Vdubber let me know your advice, I really hope it's nothing major. I hope I didn't make a mistake switching from american/japanese cars. THANKS!
Answers:
and if you look, you will count 4 injectors for each cylander
and 1 injector on the intake manifold called the cold start valve and is used only when the coolant temp sensor tells
the system that the block is cold enough for a choke, so that high idle is normal, as far as the bump bump,i would change the fuel filter about 20-25 $ and spray the coil and wires and cap, with a plant mister . i had a intermitent bad coil wire with the same systems that drove me nuts
I cant find the color of my ford anywhere on the internet i looked?
well, all cars idle high when they're cold . go to autozone and have them plug up a computer. it could be as simple as getting a new gas cap or a maybe ignitors or plugs.Check / change your spark plugs. People who sell used cars rarely put money into them. Please use factory NGK's - yes ngk. A Bosch plug will exhibit all kinds of weird engine behavior for some reason. I would start there first. Then check the ignition coil with water and a spray bottle to mist the water and listen for a ticking electric sparking sound. The coils are junk on those cars, the case cracks and leak out spark, especially under load.
Where can i sell used ford truck parts?
this kind of issue is absolutely impossible to solve in this manner. You need to have it looked at by a professional. Any well intentioned person could answer this but someone with real experience will know that this problem could be caused by many different situations. Go to your trusted mechanic or dealer and tell them you want it diagnosed and give them a price limit you are willing to spend (say an hour).www.europeanexcellenceauto.com
